Method Detail

forEach

void forEach(@NotNull
             java.util.function.Consumer<EngineReplication.ReplicationEntry> consumer)

hasNext

boolean hasNext()

dirtyEntries

void dirtyEntries(long fromTimeStamp)
           throws InterruptedException

Dirties all entries with a modification time equal to fromTimeStamp or newer. It means all these entries will be considered as "new" by this ModificationIterator and iterated once again no matter if they have already been.

This functionality is used to publish recently modified entries to a new remote node as it connects.

Parameters:

fromTimeStamp - the timestamp from which all entries should be dirty

Throws:

InterruptedException

setModificationNotifier

void setModificationNotifier(@NotNull
                             EngineReplication.ModificationNotifier modificationNotifier)

the modificationNotifier is called when ever there is a change applied to the modification iterator

Parameters:

modificationNotifier - gets notified when a change occurs
