A selection service tracks the selection within an object.
A listener that wants to be notified when the selection becomes
null must implement the INullSelectionListener
interface.
This interface is not intended to be implemented by clients.

public void addSelectionListener(ISelectionListener listener)
listener - a selection listener
public void addSelectionListener(String partId,
ISelectionListener listener)
When the part is created, the listener is passed the part's initial selection.
When the part is disposed, the listener is passed a null selection,
but only if the listener implements INullSelectionListener.
Note: This will not correctly track editor parts as each editor does not have a unique partId.
