Method Detail

entryInserted

public void entryInserted(MapEvent evt)

Invoked when a map entry has been inserted.

Specified by:

entryInserted in interface MapListener

Parameters:

evt - the MapEvent carrying the insert information

entryUpdated

public void entryUpdated(MapEvent evt)

Invoked when a map entry has been updated.

Specified by:

entryUpdated in interface MapListener

Parameters:

evt - the MapEvent carrying the update information

entryDeleted

public void entryDeleted(MapEvent evt)

Invoked when a map entry has been removed.

Specified by:

entryDeleted in interface MapListener

Parameters:

evt - the MapEvent carrying the delete information

processDeletedEntry

protected void processDeletedEntry(Object oKey,
                                   Object oValueOld)

Process an entry that is about to be removed from the internal cache. This method is called after the entry has been successfully locked, but before any listeners are notified.

If the entry is queued to be inserted or updated, then that must occur (be persisted) before we notify any listeners that it has been removed from the internal cache, otherwise (for example) if this server dies and it has the only copy of the pending update then the update will be lost!

Parameters:

oKey - the key

oValueOld - the old value

dispatch

protected void dispatch(MapEvent evt)

Dispatch the event to the corresponding listeners.

Parameters:

evt - the MapEvent object
