Class Description

The interface for creating, adding, removing and keeping track of meta-data on max Animatables.

Meta-data are custom attributes that contain only a parameter block. In order to create meta-data, you have to create its definition by specify the parameters first. This will give you a meta-data ID. You can then use that ID to add, remove or list meta-data in the scene.

virtual MetaDataID CreateMetaDataDefinition	(	const MCHAR *	in_custAttribSetName,
		const MCHAR *	in_rollOutName,
		const Tab< ParamDescriptor > &	in_paramDefs,
		MSTR *	out_errMsg = `NULL`
	)

pure virtual

Create a meta-data definition for further use in meta-data manager functions.

The ID returned will allow the user to add or remove meta-data in the scene and to keep track of them.

Parameters

in_custAttribSetName	- a name for the custom attribute set.
in_rollOutName	- a name for an eventual rollout.
in_paramDefs	- an array of descriptions for each parameter in the param block.
out_errMsg	- (optional): pointer to a MSTR. If non-null and the definition cannot be created, will contain a description of the reason.

Returns

EmptyMetaDataID if for any reason the definition cannot be created:

invalid parameter description
the definitionID already exists any other MetaDataID value if the definition was created successfully

virtual CustAttrib* AddMetaDataToAnimatable	(	const MetaDataID &	in_metaDataID,
		Animatable &	in_animatable,
		int	in_rank = `-1`
	)

pure virtual

Create a meta-data instance and add it to the custom attribute container of an animatable.

If the meta-data already exists for an animatable, it will not get added.

Parameters

in_metaDataID	- the meta-data ID of the custom attribute set to be created.
in_animatable	- the Animatable to which the custom attribute set will be added.
in_rank	- the insertion index of the custom attribute. Default is to append

Returns: the MetaData if created successfully, NULL otherwise

virtual void AddMetaDataToAnimatables	(	const MetaDataID &	in_metaDataID,
		const Tab< Animatable * > &	in_animatables,
		Tab< CustAttrib * > &	out_metaData,
		bool	in_shared = `false`,
		int	in_rank = `-1`
	)

pure virtual

Create meta-data instances and add it to the custom attribute container of animatables.

If the meta-data already exists for an animatable, it will not get added.

Parameters

in_metaDataID	- the meta-data ID of the custom attribute set to be created.
in_animatables	- an array of Animatables to which the custom attribute set will be added.
out_metaData	- an array of MetaData that were created successfully.
in_shared	- if true, a single instance will be created and shared by all animatables.
in_rank	- the insertion index of the custom attribute. Default is to append

virtual bool RemoveMetaDataFromAnimatable	(	const MetaDataID &	in_metaDataID,
		Animatable &	in_animatable
	)

pure virtual

Remove a meta-data from the custom attribute container of an animatable.

Parameters

in_metaDataID	- the meta-data ID of the custom attribute to be removed.
in_animatable	- the Animatable from which the custom attribute set will be removed.

Returns: true if the MetaData was removed

virtual int MetaDataCount ( ) const

pure virtual

Returns the number of meta-data in the scene.

virtual void GetAllMetaDataOwners	(	const MetaDataID &	in_ID,
		Tab< Animatable * > &	out_owners
	)

pure virtual

Finds all owners of meta-data of a given meta-data ID.

Parameters

in_ID	- the meta-data ID of the meta-data.
out_owners	- an array of Animatables that own meta-data of the given ID.

virtual bool IsMetaDataDefined ( const MetaDataID & in_ID ) const

pure virtual

Returns whether a definition exists for a given meta-data ID.

Parameters

in_ID - the meta-data ID to be checked.

Returns: true if the MetaData was defined.

virtual CustAttrib* GetMetaData	(	Animatable &	in_animatable,
		const MetaDataID &	in_ID
	)		const

pure virtual

Checks the existence of meta-data of a given ID on an animatable.

Parameters

in_animatable	- the animatable to be checked for meta-data.
in_ID	- the meta-data ID to be checked.

Returns: the meta-data if it exists.

virtual void GetAllMetaData	(	Animatable &	in_animatable,
		Tab< CustAttrib * > &	out_metaData
	)		const

pure virtual

Finds all meta-data on an animatable.

Parameters

in_animatable	- the animatable to be checked for meta-data.
out_metaData	- an array of the meta-data on the Animatable.
