Member Function Documentation

◆ GetAddressOfArg()

virtual void * asIScriptGeneric::GetAddressOfArg ( asUINT arg )

pure virtual

Parameters

[in] arg The argument index.

Returns: A pointer to the argument value.

◆ GetAddressOfReturnLocation()

virtual void * asIScriptGeneric::GetAddressOfReturnLocation ( )

pure virtual

Returns: A pointer to the memory where the return values is to be placed.

The memory is not initialized, so if you're going to return a complex type by value you shouldn't use the assignment operator to initialize it. Instead use the placement new operator to call the type's copy constructor to perform the initialization.

new(gen->GetAddressOfReturnLocation()) std::string(myRetValue);

The placement new operator works for primitive types too, so this method is ideal for writing automatically generated functions that works the same way for all types.

◆ GetArgAddress()

virtual void * asIScriptGeneric::GetArgAddress ( asUINT arg )

pure virtual

Parameters

[in] arg The argument index.

Returns: The address argument value, which can be a reference or and object handle.

Don't release the pointer if this is an object or object handle, the asIScriptGeneric object will do that for you.

◆ GetArgByte()

virtual asBYTE asIScriptGeneric::GetArgByte ( asUINT arg )

pure virtual

Parameters

[in] arg The argument index.

Returns: The 1 byte argument value.

◆ GetArgCount()

virtual int asIScriptGeneric::GetArgCount ( ) const

pure virtual

Returns: The number of arguments to the function.

◆ GetArgDouble()

virtual double asIScriptGeneric::GetArgDouble ( asUINT arg )

pure virtual

Parameters

[in] arg The argument index.

Returns: The double argument value.

◆ GetArgDWord()

virtual asDWORD asIScriptGeneric::GetArgDWord ( asUINT arg )

pure virtual

Parameters

[in] arg The argument index.

Returns: The 4 byte argument value.

◆ GetArgFloat()

virtual float asIScriptGeneric::GetArgFloat ( asUINT arg )

pure virtual

Parameters

[in] arg The argument index.

Returns: The float argument value.

◆ GetArgObject()

virtual void * asIScriptGeneric::GetArgObject ( asUINT arg )

pure virtual

Parameters

[in] arg The argument index.

Returns: A pointer to the object argument, which can be an object value or object handle.

Don't release the pointer if this is an object handle, the asIScriptGeneric object will do that for you.

◆ GetArgQWord()

virtual asQWORD asIScriptGeneric::GetArgQWord ( asUINT arg )

pure virtual

Parameters

[in] arg The argument index.

Returns: The 8 byte argument value.

◆ GetArgTypeId()

virtual int asIScriptGeneric::GetArgTypeId	(	asUINT	arg,
		asDWORD *	flags = `0`
	)		const

pure virtual

Parameters

[out]	flags	A combination of asETypeModifiers.

Returns: The type id of the argument.

◆ GetArgWord()

virtual asWORD asIScriptGeneric::GetArgWord ( asUINT arg )

pure virtual

Parameters

pure virtual

Returns: A pointer to the engine.

◆ GetFunction()

virtual asIScriptFunction * asIScriptGeneric::GetFunction ( ) const

pure virtual

Returns: The function that is being called.

◆ GetObject()

virtual void * asIScriptGeneric::GetObject ( )

pure virtual

Returns: A pointer to the object, if this is a method.

◆ GetObjectTypeId()

virtual int asIScriptGeneric::GetObjectTypeId ( ) const

pure virtual

Returns: The type id of the object if this is a method.

◆ GetReturnTypeId()

virtual int asIScriptGeneric::GetReturnTypeId ( asDWORD * flags = 0 ) const

pure virtual

Parameters

[out] flags A combination of asETypeModifiers.

Returns: The type id of the return value.

◆ SetReturnAddress()

virtual int asIScriptGeneric::SetReturnAddress ( void * addr )

pure virtual

Parameters

[in] addr The return value, which is an address.

Returns: A negative value on error.

Return values

asINVALID_TYPE The return type is not a reference or handle.

Sets the address return value. If it is an object handle and the application will keep a reference for later use, then the reference counter must be incremented.

◆ SetReturnByte()

virtual int asIScriptGeneric::SetReturnByte ( asBYTE val )

pure virtual

Parameters

[in] val The return value.

Returns: A negative value on error.

Return values

asINVALID_TYPE The return type is not an 8-bit value. Sets the 1 byte return value.

◆ SetReturnDouble()

virtual int asIScriptGeneric::SetReturnDouble ( double val )

pure virtual

Parameters

[in] val The return value.

Returns: A negative value on error.

Return values

asINVALID_TYPE The return type is not a 64-bit value. Sets the double return value.

◆ SetReturnDWord()

virtual int asIScriptGeneric::SetReturnDWord ( asDWORD val )

pure virtual

Parameters

[in] val The return value.

Returns: A negative value on error.

Return values

asINVALID_TYPE The return type is not a 32-bit value. Sets the 4 byte return value.

◆ SetReturnFloat()

virtual int asIScriptGeneric::SetReturnFloat ( float val )

pure virtual

Parameters

[in] val The return value.

Returns: A negative value on error.

Return values

asINVALID_TYPE The return type is not a 32-bit value. Sets the float return value.

◆ SetReturnObject()

virtual int asIScriptGeneric::SetReturnObject ( void * obj )

pure virtual

Parameters

[in] obj A pointer to the object return value.

Returns: A negative value on error.

Return values

asINVALID_TYPE The return type is not an object value or handle.

If the function returns an object, the library will automatically do what is necessary based on how the object was declared, i.e. if the function was registered to return a handle then the library will call the addref behaviour. If it was registered to return an object by value, then the library will make a copy of the object.

◆ SetReturnQWord()

virtual int asIScriptGeneric::SetReturnQWord ( asQWORD val )

pure virtual

Parameters

[in] val The return value.

Returns: A negative value on error.

Return values

asINVALID_TYPE The return type is not a 64-bit value. Sets the 8 byte return value.

◆ SetReturnWord()

virtual int asIScriptGeneric::SetReturnWord ( asWORD val )

pure virtual

Parameters

[in] val The return value.

Returns: A negative value on error.

Return values

asINVALID_TYPE The return type is not a 16-bit value. Sets the 2 byte return value.
