Detailed Description
supports quick access to the information if a container currently contains elements.
The XContainer interface is provided for containers which need to broadcast changes within the container; that means the actions of adding or removing elements are broadcast to the listeners.
This can be useful for UI to enable/disable some functions without actually accessing the data.
