Instance Attribute Details
- (CFTreeCopyDescriptionCallBack) copyDescription
The callback used to provide a description of the info field.
- (CFTreeReleaseCallBack) release
The callback used to release a previously retained info field. If this parameter is not a pointer to a function of the correct prototype, the behavior is undefined. This value may be NULL.
- (CFTreeRetainCallBack) retain
The callback used to retain the info field. If this parameter is not a pointer to a function of the correct prototype, the behavior is undefined. This value may be NULL.
- (CFIndex) version
The version number of the structure type being passed in as a parameter to a CFTree creation function. This structure is version 0.
