public interface DocumentListener
extends EventListener
Interface for an observer to register to receive notifications
of changes to a text document.
The default implementation of
the Document interface (AbstractDocument) supports asynchronous
mutations. If this feature is used (i.e. mutations are made
from a thread other than the Swing event thread), the listeners
will be notified via the mutating thread. This means that
if asynchronous updates are made, the implementation of this
interface must be threadsafe!
The DocumentEvent notification is based upon the JavaBeans
event model. There is no guarantee about the order of delivery
to listeners, and all listeners must be notified prior to making
further mutations to the Document. This means implementations
of the DocumentListener may not mutate the source of the event
(i.e. the associated Document).

- Parameters:
e - the document event
removeUpdate
public void removeUpdate(DocumentEvent e)
