pure virtual

Parameters

[out] length The length of the byte code buffer in DWORDs

Returns: A pointer to the byte code buffer, or 0 if this is not a script function.

This function is used by the asIJITCompiler to obtain the byte code buffer for building the native machine code representation.

◆ GetConfigGroup()

virtual const char * asIScriptFunction::GetConfigGroup ( ) const

pure virtual

Returns: The name of the config group, or null if not in any group.

◆ GetDeclaration()

virtual const char * asIScriptFunction::GetDeclaration	(	bool	includeObjectName = `true`,

	)		const

pure virtual

Parameters

[in]	includeObjectName	Indicate whether the object name should be prepended to the function name
[in]	includeNamespace	Indicates whether the namespace should be prepended to the function name and types
[in]	includeParamNames	Indicates whether parameter names should be added to the declaration

Returns: A null terminated string with the function declaration.

The parameter names are not stored for virtual methods. If you want to know the name of parameters to class methods, be sure to get the actual implementation rather than the virtual method.

The namespace will always be included for types that are declared in a different namespace than the function itself.

The returned value can be null if the module doesn't exist anymore, or if the function is not owned by any module, e.g. registered by the application or it is a delegate.

◆ GetModuleName()

virtual const char * asIScriptFunction::GetModuleName ( ) const

pure virtual

Returns: A null terminated string with the module name.

virtual asUINT asIScriptFunction::GetParamCount ( ) const

pure virtual

Returns: The number of parameters.

◆ GetReturnTypeId()

◆ GetScriptSectionName()

virtual const char * asIScriptFunction::GetScriptSectionName ( ) const

pure virtual

Returns: A null terminated string with the script section name where the function was implemented.

	)

pure virtual

Parameters

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

Returns: The previous pointer stored in the context.

This method allows the application to associate a value, e.g. a pointer, with the context 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 function is destroyed. As the callback is registered with the engine, it is only necessary to do it once.
