Class ReplicationStartSyncMessage

java.lang.Object

org.apache.activemq.artemis.core.protocol.core.impl.PacketImpl

org.apache.activemq.artemis.core.protocol.core.impl.wireformat.ReplicationStartSyncMessage

All Implemented Interfaces:

Packet

public class ReplicationStartSyncMessage
extends PacketImpl

This message may signal start or end of the replication synchronization.

At start, it sends all fileIDs used in a given journal live server to the backup, so the backup can reserve those IDs.

Method Detail

expectedEncodeSize

public int expectedEncodeSize()

Description copied from interface: Packet

This will return the expected packet size for the encoding

Returns:

encodeRest

public void encodeRest(ActiveMQBuffer buffer)

Overrides:

encodeRest in class PacketImpl

decodeRest

public void decodeRest(ActiveMQBuffer buffer)

Overrides:

decodeRest in class PacketImpl

isServerToFailBack

public boolean isServerToFailBack()

Returns:

whether the server is configured to allow for fail-back

isSynchronizationFinished

public boolean isSynchronizationFinished()

Returns:

true if the live has finished synchronizing its data and the backup is therefore up-to-date, false otherwise.

getDataType

public ReplicationStartSyncMessage.SyncDataType getDataType()

getFileIds

public long[] getFileIds()

getNodeID

public String getNodeID()

hashCode

public int hashCode()

Overrides:

hashCode in class PacketImpl

equals

public boolean equals(Object obj)

Overrides:

equals in class PacketImpl

toString

public String toString()

Overrides:

toString in class PacketImpl
