Method Detail

addListener

public void addListener(IResourceChangeListener listener,
                        int eventMask)

beginAvoidNotify

public boolean beginAvoidNotify()

Indicates the beginning of a block where periodic notifications should be avoided. Returns true if notification avoidance really started, and false for nested operations.

beginNotify

public void beginNotify()

Signals the beginning of the notification phase at the end of a top level operation.

broadcastChanges

public void broadcastChanges(ElementTree lastState,
                             ResourceChangeEvent event,
                             boolean lockTree)

The main broadcast point for notification deltas

broadcastChanges

public void broadcastChanges(IResourceChangeListener listener,
                             int type,
                             IResourceDelta delta)

Helper method for the save participant lifecycle computation.

endAvoidNotify

public void endAvoidNotify()

Indicates the end of a block where periodic notifications should be avoided.

requestNotify

public void requestNotify()

Requests that a periodic notification be scheduled

handleEvent

public void handleEvent(LifecycleEvent event)

Specified by:

handleEvent in interface ILifecycleListener

removeListener

public void removeListener(IResourceChangeListener listener)

shouldNotify

public boolean shouldNotify()

Returns true if a notification is needed. This happens if sufficient time has elapsed since the last notification

Specified by:

shutdown in interface IManager

startup

public void startup(org.eclipse.core.runtime.IProgressMonitor monitor)

Specified by:
