Detailed Description

The engine is the central object. It is where the application registers the application interface that the scripts should be able to use, and it is where the application can request modules to build scripts and contexts to execute them.

The engine instance is created with a call to asCreateScriptEngine.

It is allowed to have multiple instances of script engines, but there is rarely a need for it. Even if the application needs to expose different interfaces to different types of scripts this can usually be accomplished through the use of configuration groups and access profiles.

Member Function Documentation

◆ AddRef()

virtual int asIScriptEngine::AddRef ( ) const

pure virtual

Returns: The number of references to this object.

Call this method when storing an additional reference to the object. Remember that the first reference that is received from asCreateScriptEngine is already accounted for.

◆ AddRefScriptObject()

virtual void asIScriptEngine::AddRefScriptObject	(	void *	obj,
		const asITypeInfo *	type
	)

pure virtual

Parameters

[in]	obj	A pointer to the object.
[in]	type	The type of the object.

This calls the add ref method of the object to increase the reference count.

◆ AssignScriptObject()

virtual int asIScriptEngine::AssignScriptObject	(	void *	dstObj,
		void *	srcObj,
		const asITypeInfo *	type
	)

pure virtual

Parameters

[in]	dstObj	A pointer to the destination object.
[in]	srcObj	A pointer to the source object.
[in]	type	The type of the objects.

Returns: A negative value on error

Return values

asINVALID_ARG	One of the arguments is null
asNOT_SUPPORTED	The object type is a ref type and value assignment has been turned off, or the object doesn't have an appropriate assignment operator.

This calls the assignment operator to copy the object from one to the other.

This only works for objects.

◆ BeginConfigGroup()

virtual int asIScriptEngine::BeginConfigGroup ( const char * groupName )

pure virtual

Parameters

[in] groupName The name of the configuration group

Returns: A negative value on error

Return values

asNAME_TAKEN	Another group with the same name already exists.
asNOT_SUPPORTED	Nesting configuration groups is not supported.

Starts a new dynamic configuration group. This group can be setup so that it is only visible to specific modules, and it can also be removed when it is no longer used.

See also: Dynamic configurations

◆ ClearMessageCallback()

virtual int asIScriptEngine::ClearMessageCallback ( )

pure virtual

Returns: A negative value on error.

Call this method to remove the message callback.

◆ CreateContext()

virtual asIScriptContext * asIScriptEngine::CreateContext ( )

pure virtual

Returns: A pointer to the new script context.

This method creates a context that will be used to execute the script functions. The context interface created will have its reference counter already increased.

See also: RequestContext

◆ CreateDelegate()

virtual asIScriptFunction * asIScriptEngine::CreateDelegate	(	asIScriptFunction *	func,
		void *	obj
	)

pure virtual

Parameters

[in]	func	The object method
[in]	obj	The object pointer

Returns: The new delegate instance

◆ CreateScriptObject()

virtual void * asIScriptEngine::CreateScriptObject ( const asITypeInfo * type )

pure virtual

Parameters

[in] type The type of the object to create.

Returns: A pointer to the new object if successful, or null if not.

This method is used to create an object based on it's type. The method will call the object type's default factory. If the object type doesn't have a default factory the call will fail and no object will be created.

Created objects will have their reference counter set to 1 so the application needs to release the pointer when it will no longer use it.

If the type is a registered value type, then the memory for the object will be allocated using the default memory routine. To destroy and and deallocate the object it is best to use ReleaseScriptObject.

The method only works for objects, for primitive types and object handles the method doesn't do anything and returns a null pointer.

◆ CreateScriptObjectCopy()

virtual void * asIScriptEngine::CreateScriptObjectCopy	(	void *	obj,
		const asITypeInfo *	type
	)

pure virtual

Parameters

[in]	obj	A pointer to the source object.
[in]	type	The type of the object.

Returns: A pointer to the new object if successful, or null if not.

This method is used to create a copy of an existing object.

This only works for objects, for primitive types and object handles the method doesn't do anything and returns a null pointer.

◆ CreateUninitializedScriptObject()

virtual void * asIScriptEngine::CreateUninitializedScriptObject ( const asITypeInfo * type )

pure virtual

Parameters

[in] type The type of the object to create.

Returns: A pointer to the new object if successful, or null if not.

This method can only be used to create instances of script classes.

The returned object will only be initialized so far that there are no invalid pointers or references. The constructor of the script class will not be invoked.

If the script class has any registered types as members, the default constructor for those members will be executed.

This method is meant for objects that will be initialized manually by the application, e.g. when restoring a serialized object.

See also: Serialization of objects

◆ DiscardModule()

virtual int asIScriptEngine::DiscardModule ( const char * module )

pure virtual

Parameters

[in] module The name of the module

Returns: A negative value on error

Return values

asNO_MODULE The module was not found.

Discards a module and frees its memory. Any pointers that the application holds to this module will be invalid after this call.

◆ EndConfigGroup()

virtual int asIScriptEngine::EndConfigGroup ( )

pure virtual

Returns: A negative value on error

Return values

asERROR Can't end a group that hasn't been begun.

Ends the current configuration group. Once finished a config group cannot be changed, but it can be removed when it is no longer used.

See also: Dynamic configurations

◆ ForwardGCEnumReferences()

virtual void asIScriptEngine::ForwardGCEnumReferences	(	void *	ref,
		asITypeInfo *	type
	)

pure virtual

Parameters

[in]	ref	The object pointer
[in]	type	The type of the object

This should be used by reference types that implement the asBEHAVE_ENUMREFS behaviour when the object holds a value type that can in turn contain references.

See also: Garbage collected objects

◆ ForwardGCReleaseReferences()

virtual void asIScriptEngine::ForwardGCReleaseReferences	(	void *	ref,
		asITypeInfo *	type
	)

pure virtual

Parameters

[in]	ref	The object pointer
[in]	type	The type of the object

This should be used by reference types that implement the asBEHAVE_RELEASEREFS behaviour when the object holds a value type that can in turn contain references.

See also: Garbage collected objects

◆ GarbageCollect()

virtual int asIScriptEngine::GarbageCollect	(	asDWORD	flags = `asGC_FULL_CYCLE`,
		asUINT	numIterations = `1`
	)

pure virtual

Parameters

[in]	flags	Set to a combination of the asEGCFlags.
[in]	numIterations	The number of iterations to perform when not doing a full cycle

Returns: 1 if the cycle wasn't completed, 0 if it was.

This method will free script objects that can no longer be reached. When the engine is released the garbage collector will automatically do a full cycle to release all objects still alive. If the engine is long living it is important to call this method every once in a while to free up memory allocated by the scripts. If a script does a lot of allocations before returning it may be necessary to implement a line callback function that calls the garbage collector during execution of the script.

It is not necessary to do a full cycle with every call. This makes it possible to spread out the garbage collection time over a large period, thus not impacting the responsiveness of the application.

See also: Garbage collection

◆ GCEnumCallback()

virtual void asIScriptEngine::GCEnumCallback ( void * reference )

pure virtual

Parameters

[in] reference A pointer to the referenced object.

When processing the asBEHAVE_ENUMREFS call the called object should call GCEnumCallback for each of the references it holds to other objects. If the object holds a value type that may contain references, then use the ForwardGCEnumReferences.

See also: Garbage collected objects

pure virtual

Parameters

[in] decl The declaration of the type.

Returns: A negative value on error, or the type id of the type.

Return values

asINVALID_TYPE decl is not a valid type.

Translates a type declaration into a type id. The returned type id is valid for as long as the type is valid, so you can safely store it for later use to avoid potential overhead by calling this function each time. Just remember to update the type id, any time the type is changed within the engine, e.g. when recompiling script declared classes, or changing the engine configuration.

The type id is based on a sequence number and depends on the order in which the type ids are queried, thus is not guaranteed to always be the same for each execution of the application. The asETypeIdFlags can be used to obtain some information about the type directly from the id.

A base type yields the same type id whether the declaration is const or not, however if the const is for the subtype then the type id is different, e.g. string@ isn't the same as const string@ but string is the same as const string.

This method is only able to return the type id that are not specific for a script module, i.e. built-in types and application registered types. Type ids for script declared types should be obtained through the script module's GetTypeIdByDecl.

◆ GetTypeInfoByDecl()

virtual asITypeInfo * asIScriptEngine::GetTypeInfoByDecl ( const char * decl ) const

pure virtual

Parameters

[in] decl The declaration of the type.

Returns: The type or null on error.

Translates a type declaration into the type info. The returned type is valid for as long as the type is valid, so you can safely store it for later use to avoid potential overhead from calling this function each time. Just remember to update the type info pointer any time the type is changed within the engine, e.g. when recompiling script declared classes, or changing the engine configuration.

◆ GetTypeInfoById()

virtual asITypeInfo * asIScriptEngine::GetTypeInfoById ( int typeId ) const

pure virtual

Parameters

[in] typeId The type id of the type.

Returns: The type interface for the type, or null if not found.

This does not increment the reference count of the returned type.

◆ GetTypeInfoByName()

virtual asITypeInfo * asIScriptEngine::GetTypeInfoByName ( const char * name ) const

pure virtual

Parameters

[in] name The name of the type.

Returns: The type interface for the type, or null if not found.

The search for types will be performed in the default namespace as given by SetDefaultNamespace unless the name is prefixed with a scope, using the scoping operator ::. If the scope starts with :: it will be used as the absolute scope, otherwise it will be relative to the default namespace.

◆ GetUserData()

virtual void * asIScriptEngine::GetUserData ( asPWORD type = 0 ) const

pure virtual

Parameters

[in] type An identifier specifying the user data to get.

Returns: The pointer to the user data.

◆ GetWeakRefFlagOfScriptObject()

virtual asILockableSharedBool * asIScriptEngine::GetWeakRefFlagOfScriptObject	(	void *	obj,
		const asITypeInfo *	type
	)		const

pure virtual

Parameters

[in]	obj	The object
[in]	type	The object type

Returns: The weak ref flag, if the object supports weak references.

As long as the weak ref flag is not set, the owning object is still alive. Once the weak ref flag is set, the object is dead and should no longer be accessed. Check if the flag is set with the asILockableSharedBool::Get method.

This method doesn't increase the reference to the returned shared boolean.

◆ NotifyGarbageCollectorOfNewObject()

virtual int asIScriptEngine::NotifyGarbageCollectorOfNewObject	(	void *	obj,
		asITypeInfo *	type
	)

pure virtual

Parameters

[in]	obj	A pointer to the newly created object.
[in]	type	The type of the object.

Returns: The sequence number of the added object, or a negative value on error.

Return values

asINVALID_ARG Either the object or the type is null

This method should be called when a new garbage collected object is created. The GC will then store a reference to the object so that it can automatically detect whether the object is involved in any circular references that should be released.

See also: Garbage collected objects

◆ ParseToken()

virtual asETokenClass asIScriptEngine::ParseToken	(	const char *	string,
		size_t	stringLength = `0`,
		asUINT *	tokenLength = `0`
	)		const

pure virtual

Parameters

[in]	string	The string to parse.
[in]	stringLength	The length of the string. Can be 0 if the string is null terminated.
[out]	tokenLength	Gives the length of the identified token.

Returns: One of the asETokenClass values.

This function is useful for those applications that want to tokenize strings into tokens that the script language uses, e.g. IDEs providing syntax highlighting, or intellisense. It can also be used to parse the meta data strings that may be declared for script entities.

◆ RefCastObject()

virtual int asIScriptEngine::RefCastObject	(	void *	obj,
		asITypeInfo *	fromType,
		asITypeInfo *	toType,
		void **	newPtr,
		bool	useOnlyImplicitCast = `false`
	)

pure virtual

Parameters

[in]	obj	A pointer to the object.
[in]	fromType	The type of the object.
[in]	toType	The desired type for the cast.
[out]	newPtr	The new pointer to the object if successful.
[in]	useOnlyImplicitCast	If only the implicit reference cast operators should be used.

Returns: A negative value on error

Return values

asINVALID_ARG A null pointer was supplied

This method is used to cast an pointer to a different type. While both the new and old pointers are expected to refer to the same instance, the address of the pointers are not necessarily the same.

If the cast is successful the newPtr will be set to the new pointer, and the reference counter will be incremented. If the cast is not successful, the newPtr will be set to null, and the reference count left unchanged.

◆ RegisterDefaultArrayType()

virtual int asIScriptEngine::RegisterDefaultArrayType ( const char * type )

pure virtual

Parameters

[in] type The name of the template type, e.g. array<T>

Returns: A negative value on error.

Return values

asINVALID_TYPE The type is not a template type

◆ RegisterEnum()

virtual int asIScriptEngine::RegisterEnum ( const char * type )

pure virtual

Parameters

[in] type The name of the enum type.

Returns: The type id on success, or a negative value on error.

Return values

asINVALID_NAME	type is null, not an identifier, or it is a reserved keyword.
asALREADY_REGISTERED	Another type with this name already exists.
asERROR	The type couldn't be parsed.
asNAME_TAKEN	The type name is already taken.

This method registers an enum type in the engine. The enum values should then be registered with RegisterEnumValue.

◆ RegisterEnumValue()

virtual int asIScriptEngine::RegisterEnumValue	(	const char *	type,
		const char *	name,
		int	value
	)

pure virtual

Parameters

[in]	type	The name of the enum type.
[in]	name	The name of the enum value.

◆ RegisterFuncdef()

virtual int asIScriptEngine::RegisterFuncdef ( const char * decl )

pure virtual

Parameters

[in] decl The declaration of the function definition.

Returns: The type id on success, else a negative value on error.

Return values

asINVALID_ARG	The decl parameter is not given.
asINVALID_DECLARATION	decl is not a valid function definition.
asNAME_TAKEN	The name of the funcdef conflicts with another name.

Funcdefs are used to define the signature of function pointers. If the application is going to receive function pointers from scripts, it is necessary to first register the funcdef before registering the function or property that will be used to receive it.

Funcdefs are usually registered as global entities, but can also be registered as a child of a class. To do this simply prefix the name of the funcdef with the name of the class and the scope operator to specify which class should be the owner.

◆ RegisterGlobalFunction()

virtual int asIScriptEngine::RegisterGlobalFunction	(	const char *	declaration,
		const asSFuncPtr &	funcPointer,
		asDWORD	callConv,
		void *	auxiliary = `0`
	)

pure virtual

Parameters

[in]	declaration	The declaration of the global function in script syntax.
[in]	funcPointer	The function pointer.
[in]	callConv	The calling convention for the function.
[in]	auxiliary	A helper object for use with some calling conventions.

Returns: A negative value on error, or the function id if successful.

Return values

asNOT_SUPPORTED	The calling convention is not supported.
asWRONG_CALLING_CONV	The function's calling convention doesn't match callConv.
asINVALID_DECLARATION	The function declaration is invalid.
asNAME_TAKEN	The function name is already used elsewhere.
asALREADY_REGISTERED	The function has already been registered with the same parameter list.
asINVALID_ARG	The auxiliary pointer wasn't set according to calling convention.

This method registers system functions that the scripts may use to communicate with the host application.

The auxiliary pointer can optionally be used with asCALL_GENERIC. For the calling convention asCALL_THISCALL_ASGLOBAL the auxiliary is required.

See also: Registering a function

◆ RegisterGlobalProperty()

virtual int asIScriptEngine::RegisterGlobalProperty	(	const char *	declaration,
		void *	pointer
	)

pure virtual

Parameters

[in]	declaration	The declaration of the global property in script syntax.

Returns: The index of the property on success, or a negative value on error.

Return values

asINVALID_DECLARATION	The declaration has invalid syntax.
asINVALID_TYPE	The declaration is a reference.
asINVALID_ARG	The pointer is null.
asNAME_TAKEN	The name is already taken.

Use this method to register a global property that the scripts will be able to access as global variables. The property may optionally be registered as const, if the scripts shouldn't be allowed to modify it.

When registering the property, the application must pass the address to the actual value. The application must also make sure that this address remains valid throughout the life time of this registration, i.e. until the engine is released or the dynamic configuration group is removed.

Upon success the function returns the index of the registered property
that can be used to lookup the info with GetGlobalPropertyByIndex. Note that this index may not stay valid after a dynamic config group has been removed, which would reorganize the internal structure.

◆ RegisterInterface()

virtual int asIScriptEngine::RegisterInterface ( const char * name )

pure virtual

Parameters

[in] name The name of the interface.

Returns: The type id of the interface on success, else a negative value on error.

Return values

asINVALID_NAME	The name is null, or a reserved keyword.
asALREADY_REGISTERED	An object type with this name already exists.
asERROR	The name is not a proper identifier.
asNAME_TAKEN	The name is already used elsewhere.

This registers an interface that script classes can implement. By doing this the application can register functions and methods that receives an asIScriptObject and still be sure that the class implements certain methods needed by the application.

See also: Receiving script classes

◆ RegisterInterfaceMethod()

virtual int asIScriptEngine::RegisterInterfaceMethod	(	const char *	intf,
		const char *	declaration
	)

pure virtual

Parameters

This registers a method that the class that implements the script interface must have.

◆ RegisterObjectBehaviour()

virtual int asIScriptEngine::RegisterObjectBehaviour	(	const char *	obj,
		asEBehaviours	behaviour,
		const char *	declaration,
		const asSFuncPtr &	funcPointer,
		asDWORD	callConv,
		void *	auxiliary = `0`,
		int	compositeOffset = `0`,
		bool	isCompositeIndirect = `false`
	)

pure virtual

Parameters

[in]	obj	The name of the type.
[in]	behaviour	One of the object behaviours from asEBehaviours.
[in]	declaration	The declaration of the method in script syntax.
[in]	funcPointer	The method or function pointer.
[in]	callConv	The calling convention for the method or function.
[in]	auxiliary	A helper object for use with some calling conventions.
[in]	compositeOffset	The offset to the composite object.
[in]	isCompositeIndirect	Set to false if the composite object is inline, and true if it is refered to by pointer.

Returns: A negative value on error, or the function id is successful.

Return values

asWRONG_CONFIG_GROUP	The object type was registered in a different configuration group.
asINVALID_ARG	obj is not set, or a global behaviour is given in behaviour, or the objForThiscall pointer wasn't set according to calling convention.
asWRONG_CALLING_CONV	The function's calling convention isn't compatible with callConv.
asNOT_SUPPORTED	The calling convention or the behaviour signature is not supported.
asINVALID_TYPE	The obj parameter is not a valid object name.
asINVALID_DECLARATION	The declaration is invalid.
asILLEGAL_BEHAVIOUR_FOR_TYPE	The behaviour is not allowed for this type.
asALREADY_REGISTERED	The behaviour is already registered with the same signature.

Use this method to register behaviour functions that will be called by the virtual machine to perform certain operations, such as memory management, math operations, comparisons, etc.

The declaration must form a valid function signature, but the give function name will not be used or stored in the application so there is no need to provide a meaningful function name.

The auxiliary pointer can optionally be used with asCALL_GENERIC. For the calling conventions asCALL_THISCALL_ASGLOBAL, asCALL_THISCALL_OBJFIRST and asCALL_THISCALL_OBJLAST the auxiliary is required.

In case the method to be registered is part of a composite member, then the compositeOffset should be used to give the offset to the composite member, and the method pointer should be method of the composite member. If the composite member is inline then set isCompositeIndirect as false, else set it to true for proper indirection.

asALREADY_REGISTERED	The method has already been registered with the same parameter list.
asINVALID_ARG	The auxiliary pointer wasn't set according to calling convention.

Use this method to register a member method for the type. The method that is registered may be an actual class method, or a global function that takes the object pointer as either the first or last parameter. Or it may be a global function implemented with the generic calling convention.

The auxiliary pointer can optionally be used with asCALL_GENERIC. For the calling conventions asCALL_THISCALL_OBJFIRST and asCALL_THISCALL_OBJLAST the auxiliary is required.

In case the method to be registered is part of a composite member, then the compositeOffset should be used to give the offset to the composite member, and the method pointer should be method of the composite member. If the composite member is inline then set isCompositeIndirect as false, else set it to true for proper indirection.

		int	compositeOffset = `0`,
		bool	isCompositeIndirect = `false`
	)

pure virtual

Parameters

[in]	obj	The name of the type.
[in]	declaration	The property declaration in script syntax.
[in]	byteOffset	The offset into the memory block where this property is found.
[in]	compositeOffset	The offset to the composite object.
[in]	isCompositeIndirect	Set to false if the composite object is inline, and true if it is refered to by pointer.

Returns: The index of the property on success, or a negative value on error.

Return values

asWRONG_CONFIG_GROUP	The object type was registered in a different configuration group.
asINVALID_OBJECT	The obj does not specify an object type.
asINVALID_TYPE	The obj parameter has invalid syntax.
asINVALID_DECLARATION	The declaration is invalid.
asNAME_TAKEN	The name conflicts with other members.

Use this method to register a member property of a class. The property must be local to the object, i.e. not a global variable or a static member. The easiest way to get the offset of the property is to use the asOFFSET macro.

struct MyType {float prop;};

r = engine->RegisterObjectProperty("MyType", "float prop", asOFFSET(MyType, prop)));

asOFFSET

#define asOFFSET(s, m)

Returns the offset of an attribute in a struct.

Definition: angelscript.h:705

In case the property to be registered is part of a composite member, then the compositeOffset should be used to give the offset to the composite member, and byteOffset should be the offset to the property in that composite member. If the composite member is inline then set isCompositeIndirect as false, else set it to true for proper indirection.

The method returns the index of the property upon success. This can be used to look up the property in the object type with asITypeInfo::GetProperty.

[in]	byteSize	The size of the type in bytes. Only necessary for value types.
[in]	flags	One or more of the asEObjTypeFlags.

Returns: The type id on success or a negative value on error.

Return values

asINVALID_ARG	The flags are invalid.
asINVALID_NAME	The name is invalid.
asALREADY_REGISTERED	Another type of the same name already exists.
asNAME_TAKEN	The name conflicts with other symbol names.
asLOWER_ARRAY_DIMENSION_NOT_REGISTERED	When registering an array type the array element must be a primitive or a registered type.
asINVALID_TYPE	The array type was not properly formed.
asNOT_SUPPORTED	The array type is not supported, or already in use preventing it from being overloaded.

Use this method to register new types that should be available to the scripts. Reference types, which have their memory managed by the application, should be registered with asOBJ_REF. Value types, which have their memory managed by the engine, should be registered with asOBJ_VALUE.

[in]	factory	The pointer to the factory object

Returns: A negative value on error, or the function id if successful.

Return values

asINVALID_ARG	The factory is null.
asINVALID_TYPE	The datatype is not a valid type, or it is a reference or handle.

Use this function to register a string factory that will be called during compilation to create instances of a string constant. The string factory will also be used while saving bytecode in order to get the raw string data for serialization.

The data type that represents the string type should be informed without reference or handle token, as the script engine will assume a const reference anyway.

See also: Custom string type

asALREADY_REGISTERED	A type with the same name already exists.
asINVALID_TYPE	The decl is not a primitive type.
asNAME_TAKEN	The name is already used elsewhere.

This method registers an alias for a data type.

Currently typedefs can only be registered for built-in primitive types.

◆ Release()

virtual int asIScriptEngine::Release ( ) const

pure virtual

Returns: The number of references to this object.

Call this method when you will no longer use the references that you own.

If you know that the engine is supposed to be shut down, then it is recommended to call the ShutDownAndRelease method instead.

◆ ReleaseScriptObject()

virtual void asIScriptEngine::ReleaseScriptObject	(	void *	obj,
		const asITypeInfo *	type
	)

pure virtual

Parameters

[in]	obj	A pointer to the object.
[in]	type	The type of the object.

This calls the release method of the object to release the reference.

If the type is a value type, the method will destroy the object and deallocate the memory using the default memory routine.

◆ RemoveConfigGroup()

virtual int asIScriptEngine::RemoveConfigGroup ( const char * groupName )

pure virtual

Parameters

[in] groupName The name of the configuration group

Returns: A negative value on error

Return values

asCONFIG_GROUP_IS_IN_USE The group is in use and cannot be removed.

◆ RequestContext()

virtual asIScriptContext * asIScriptEngine::RequestContext ( )

pure virtual

Returns: An unprepared context

This method will invoke the registered request context callback and return an available context in an unprepared state.

virtual void asIScriptEngine::ReturnContext ( asIScriptContext * ctx )

pure virtual

Parameters

[in] ctx The context that should be returned to the origin

◆ SetCircularRefDetectedCallback()

virtual void asIScriptEngine::SetCircularRefDetectedCallback	(	asCIRCULARREFFUNC_t	callback,
		void *	param = `0`
	)

pure virtual

Parameters

[in]	callback	The callback function
[in]	param	Optional parameter that will be passed back to the callback function

This callback is meant to be used during development to help identify scripts that are creating circular references. As the callback will be invoked when the objects in the circular reference are detected, but before they are destroyed, the application can investigate their content to get hints where the objects are created from.

See also: Garbage collection

◆ SetContextCallbacks()

virtual int asIScriptEngine::SetContextCallbacks	(	asREQUESTCONTEXTFUNC_t	requestCtx,
		asRETURNCONTEXTFUNC_t	returnCtx,
		void *	param = `0`
	)

pure virtual

This method can be used by the application to implement a context pool, or to perform custom configuration on the contexts that the engine uses internally.

This can for example be used to debug calls to initialize global variables when building modules, or to detect script exceptions that may occur in script class destructors when called from the garbage collector.

◆ SetContextUserDataCleanupCallback()

virtual void asIScriptEngine::SetContextUserDataCleanupCallback	(	asCLEANCONTEXTFUNC_t	callback,
		asPWORD	type = `0`
	)

pure virtual

Parameters

asFUNCTION

#define asFUNCTION(f)

Returns an asSFuncPtr representing the function specified by the name.

Definition: angelscript.h:708

It is recommended to register the message callback routine right after creating the engine, as some of the registration functions can provide useful information to better explain errors.

asWRONG_CALLING_CONV	callConv isn't compatible with the routines' calling convention.

This callback function will be called by the VM when an application exception is raised, which allow the application to translate the exception into a useful string to inform in SetException.

The callback function signature must be either:

  void (*)(asIScriptContext *, void *);

or

  void (param::*)(asIScriptContext *);

See Exceptions for an example on how to use this.

◆ SetTypeInfoUserDataCleanupCallback()

virtual void asIScriptEngine::SetTypeInfoUserDataCleanupCallback	(	asCLEANTYPEINFOFUNC_t	callback,
		asPWORD	type = `0`
	)

pure virtual

Parameters

[in]	callback	A pointer to the function
[in]	type	An identifier specifying which user data the callback is to be used with.

The function given with this call will be invoked when a type info is destroyed if any user data has been registered with the type.

The function is called from within the type info destructor, so the callback should not be used for anything but cleaning up the user data itself.

◆ SetUserData()

virtual void * asIScriptEngine::SetUserData	(	void *	data,
		asPWORD	type = `0`
	)

pure virtual

Parameters

[in]	data	A pointer to the user data.
[in]	type	An identifier specifying the user data to set.

Returns: The previous pointer stored in the engine.

This method allows the application to associate a value, e.g. a pointer, with the engine instance.

The type values 1000 through 1999 are reserved for use by the official add-ons.

Optionally, a callback function can be registered to clean up the user data when the engine is destroyed.

◆ ShutDownAndRelease()

virtual int asIScriptEngine::ShutDownAndRelease ( )

pure virtual

Returns: The number of references to this object.

Call this method when you know it is time to shut down the engine. This will automatically discard all the script modules and run a complete garbage collection cycle.

Calling this method rather than the ordinary Release method will avoid potential memory leaks if for example there are objects in the modules or garbage collector that indirectly holds a reference to the engine.

◆ WriteMessage()

virtual int asIScriptEngine::WriteMessage	(	const char *	section,
		int	row,
		int	col,
		asEMsgType	type,
		const char *	message
	)

pure virtual

Parameters

[in]	section	The name of the script section.
[in]	row	The row number.
[in]	col	The column number.
[in]	type	The message type.
[in]	message	The message text.

Returns: A negative value on error.

Return values

asINVALID_ARG The section or message is null.

This method can be used by the application to write messages to the same message callback that the script compiler uses. This is useful for example if a preprocessor is used.
