Method Detail

addEvent

public void addEvent(com.hazelcast.wan.WanReplicationEvent event)

Adds a WAN event to the batch. Depending on the whether snapshot is enabled, the event may be coalesced with an another event with the same key or not.

Parameters:

event - a WAN replication event

WanReplicationProperties.SNAPSHOT_ENABLED

getPrimaryEventCount

public int getPrimaryEventCount()

Returns the number of non-sync WAN events added to this batch. This may be different than the size of the getEvents() if snapshotEnabled is true.

getTotalEntryCount

public int getTotalEntryCount()

Returns the total number of WAN events in this batch, including WAN sync events and merkle tree node entries. This may differ from other counts, such as the size of the getEvents() and the getPrimaryEventCount().

getCoalescedEvents

public List<com.hazelcast.wan.WanReplicationEvent> getCoalescedEvents()

Returns all events which were coalesced by other newer events in getEvents().

getEvents

public Collection<com.hazelcast.wan.WanReplicationEvent> getEvents()

Returns the WAN events in this batch
