The com.sun.star.lang.XEventListener interface is the base for all listener interfaces . This means that not only XEventListeners, but every listener must implement disposing(), and every broadcaster object that allows any kind of listener to register, must call disposing() on the listeners as soon as it dies. However, not every broadcaster is forced to implement the XComponent interface with the dispose() method, because it may define its own condition when it is disposed.

In a chain of broadcaster objects where every element is a listener of its predecessor and only the root object is an XComponent that is being disposed, all the other chain links must handle the disposing() call coming from their predecessor and call disposing() on their registered listeners.
