• java.lang.Object

Fields Summary
private final List	mInfos

Constructors Summary
public NotificationListenerTracking(boolean synchronize) final List<NotificationListenerInfo> infos = new ArrayList<NotificationListenerInfo>(); mInfos = synchronize ? Collections.synchronizedList( infos ) : infos;

Methods Summary
public void	addNotificationListener(javax.management.NotificationListener listener, javax.management.NotificationFilter filter, java.lang.Object handback) final NotificationListenerInfo info = new NotificationListenerInfo( listener, filter, handback ); mInfos.add( info );
public int	getListenerCount() return mInfos.size();
private final boolean	handbacksEqual(java.lang.Object handback1, java.lang.Object handback2) return( handback1 == handback2 );
private final boolean	listenersEqual(javax.management.NotificationListener listener1, javax.management.NotificationListener listener2) return( listener1 == listener2 );
public java.util.List	removeNotificationListener(javax.management.NotificationListener listener) Remove all instances of the specified listener and return their corresponding NotificationListenerInfo. This behavior matches the behavior of {@link javax.management.NotificationEmitter}. return list of NotificationListenerInfo final Iterator iter = mInfos.iterator(); final List<NotificationListenerInfo> results = new ArrayList<NotificationListenerInfo>(); while( iter.hasNext() ) { final NotificationListenerInfo info = (NotificationListenerInfo)iter.next(); if ( listenersEqual( listener, info.getListener() ) ) { iter.remove(); results.add( info ); } } return( results );
public NotificationListenerInfo	removeNotificationListener(javax.management.NotificationListener listener, javax.management.NotificationFilter filter, java.lang.Object handback) Remove the first instance of the specified listener/filter/handback combination and return its corresponding NotificationListenerInfo. This behavior matches the behavior of {@link javax.management.NotificationEmitter}. return list of NotificationListenerInfo final Iterator iter = mInfos.iterator(); NotificationListenerInfo result = null; while( iter.hasNext() ) { final NotificationListenerInfo info = (NotificationListenerInfo)iter.next(); if ( listenersEqual( listener, info.getListener() ) && handbacksEqual( handback, info.getHandback() ) ) { iter.remove(); result = info; break; } } return( result );
