Method Detail

public void close()

Specified by:

Specified by:

close in interface java.lang.AutoCloseable

notifyChange

public void notifyChange(NegotiationEvent e)

Description copied from interface: Listener

a notification call that occurs when something changed. Consult the parent object for details about this event.

NOTICE 1

notifications run in the thread of the caller. The caller will be blocked until this callback has been completed. It is therfore good practice to handle callbacks quickly.

NOTICE 2

Notifications often cross a thread sarety boundary. For example when in MVC a model (typically thread safe) calls back a panel (not thread safe). The called side (the panel) thus must handle the callback in a thread safe manner, e.g. using SwingUtilities.invokeLater(Runnable). We recommend to avoid synchronize as this will can block indefinitely (see notice 1) which might lead to deadlocks.

Specified by:

notifyChange in interface Listener<NegotiationEvent>

Parameters:

e - additional data, typically the new value associated with the event
