Interface EntryListenerFlags

All Known Subinterfaces:
TableEntryListener
public interface EntryListenerFlags
Flag values for use with entry listeners.

The flags are a bitmask and must be OR'ed together to indicate the combination of events desired to be received.

The constants kNew, kDelete, kUpdate, and kFlags represent different events that can occur to entries.

By default, notifications are only generated for remote changes occurring after the listener is created. The constants kImmediate and kLocal are modifiers that cause notifications to be generated at other times.
