Member Function Documentation

virtual int asIObjectType::AddRef ( ) const

pure virtual

Returns: The number of references to this object.

Call this method when storing an additional reference to the object.

virtual bool asIObjectType::DerivesFrom ( const asIObjectType * objType ) const

pure virtual

Parameters

[in] objType The potential parent type.

Returns: True if the type inherits directly or indirectly from the informed type.

virtual asDWORD asIObjectType::GetAccessMask ( ) const

pure virtual

Returns: The access mask for this type.

virtual asIObjectType* asIObjectType::GetBaseType ( ) const

pure virtual

Returns: A pointer to the object type that this type derives from.

This method will only return a pointer in case of script classes that derives from another script class.

This does not increase the reference count of the returned object type.

virtual asIScriptFunction* asIObjectType::GetBehaviourByIndex	(	asUINT	index,
		asEBehaviours *	outBehaviour
	)		const

pure virtual

Parameters

[in]	index	The index of the behaviour.
[out]	outBehaviour	Receives the type of the behaviour.

Returns: The function of the behaviour, or null on error.

virtual asUINT asIObjectType::GetBehaviourCount ( ) const

pure virtual

Returns: The number of behaviours for this type.

virtual const char* asIObjectType::GetConfigGroup ( ) const

pure virtual

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

virtual asIScriptEngine* asIObjectType::GetEngine ( ) const

pure virtual

Returns: A pointer to the engine.

virtual asIScriptFunction* asIObjectType::GetFactoryByDecl ( const char * decl ) const

pure virtual

Parameters

[in] decl The declaration of the function

Returns: The matching factory function or null if there are no matches

virtual asIScriptFunction* asIObjectType::GetFactoryByIndex ( asUINT index ) const

pure virtual

Parameters

[in] index The index of the factory function.

Returns: The factory function or null if the index is invalid.

virtual asUINT asIObjectType::GetFactoryCount ( ) const

pure virtual

Returns: The number of factory functions for this object.

virtual asDWORD asIObjectType::GetFlags ( ) const

pure virtual

Returns: A bit mask with the flags from asEObjTypeFlags.

Script classes are identified by having the asOBJ_SCRIPT_OBJECT flag set. Interfaces are identified as a script class with a size of zero.

See Also: GetSize

virtual asIObjectType* asIObjectType::GetInterface ( asUINT index ) const

pure virtual

Parameters

[in] index The interface index.

Returns: A pointer to the interface type.

virtual asUINT asIObjectType::GetInterfaceCount ( ) const

pure virtual

Returns: The number of interfaces implemented by this type.

virtual asIScriptFunction* asIObjectType::GetMethodByDecl	(	const char *	decl,
		bool	getVirtual = `true`
	)		const

pure virtual

Parameters

[in]	decl	The method signature.
[in]	getVirtual	Set to true if the virtual method or the real method should be retrieved.

Returns: The method or null on error.

This method should be used to retrieve the script method for the object that you wish to execute. The method is then sent to the context's Prepare method.

The method will find the script method with the exact same declaration.

virtual asIScriptFunction* asIObjectType::GetMethodByIndex	(	asUINT	index,
		bool	getVirtual = `true`
	)		const

pure virtual

Parameters

[in]	index	The index of the method.
[in]	getVirtual	Set to true if the virtual method or the real method should be retrieved.

Returns: The method or null on error.

This method should be used to retrieve the script method for the object that you wish to execute. The method is then sent to the context's Prepare method.

By default this returns the virtual method for script classes. This will allow you to call the virtual method on classes, and rely on the polymorphism to call the correct implementation. If you wish to inspect the real method, then you should set the second parameter to false to retrieve the real method.

virtual asIScriptFunction* asIObjectType::GetMethodByName	(	const char *	name,
		bool	getVirtual = `true`
	)		const

pure virtual

Parameters

[in]	name	The name of the method.
[in]	getVirtual	Set to true if the virtual method or the real method should be retrieved.

Returns: Tthe method or null in case of error

This method should be used to retrieve the script method for the object that you wish to execute. The method is then sent to the context's Prepare method.

virtual asUINT asIObjectType::GetMethodCount ( ) const

pure virtual

Returns: The number of methods for this object.

virtual asIScriptModule* asIObjectType::GetModule ( ) const

pure virtual

Returns: The module where the type is declared.

The returned value can be null if the module doesn't exist anymore.

virtual const char* asIObjectType::GetName ( ) const

pure virtual

Returns: A null terminated string with the name of the object type.

virtual const char* asIObjectType::GetNamespace ( ) const

pure virtual

Returns: The namespace of the object type.

virtual int asIObjectType::GetProperty	(	asUINT	index,
		const char **	name,
		int *	typeId = `0`,
		bool *	isPrivate = `0`,
		bool *	isProtected = `0`,
		int *	offset = `0`,
		bool *	isReference = `0`,
		asDWORD *	accessMask = `0`
	)		const

pure virtual

Parameters

[in]	index	The index of the property
[out]	name	The name of the property
[out]	typeId	The type of the property
[out]	isPrivate	Whether the property is private or not
[out]	isProtected	Whether the property is protected or not
[out]	offset	The offset into the object where the property is stored
[out]	isReference	True if the property is not stored inline

		bool	includeNamespace = `false`
	)		const

[in]	includeNamespace	Set to true if the namespace should be included in the declaration.

Returns: The declaration of the property, or null on error.

virtual asUINT asIObjectType::GetSize ( ) const

pure virtual

Returns: The number of bytes necessary to store instances of this type.

Application registered reference types doesn't store this information, as the script engine doesn't allocate memory for these itself.

virtual asIObjectType* asIObjectType::GetSubType ( asUINT subTypeIndex = 0 ) const

pure virtual

Parameters

Returns: The object type of the template sub type, or null if the template subtype is not an object type.

virtual asUINT asIObjectType::GetSubTypeCount ( ) const

pure virtual

Returns: The number of template sub types.

virtual int asIObjectType::GetSubTypeId ( asUINT subTypeIndex = 0 ) const

pure virtual

Parameters

[in] subTypeIndex The zero based index of the template sub type.

Returns: The type id of the template sub type, or a negative value on error.

virtual int asIObjectType::GetTypeId ( ) const

pure virtual

Returns: The type id for the object type.

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

pure virtual

Parameters

[in] type An identifier used to identify which user data to get.

Returns: The pointer to the user data.

virtual bool asIObjectType::Implements ( const asIObjectType * objType ) const

pure virtual

Parameters

[in] objType The interface type.

Returns: True if the type implements the informed interface type.

virtual int asIObjectType::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.

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

pure virtual

Parameters

[in]	data	A pointer to the user data.
[in]	type	An identifier used to identify which user data to set.

Returns: The previous pointer stored in the object type.

This method allows the application to associate a value, e.g. a pointer, with the object type instance. Multiple different values can be defined where the type argument identifies which is referred to.

The user data types identifiers between 1000 and 1999 are reserved for use by official add-ons.

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