Package org.opends.server.replication.protocol
This package contains the code used by the replication server and by the code running on the Directory Server side to
exchange their information.
The main classes of this packages are :
The main classes of this packages are :
- Session implements the session and protocol that is used by the replication server and the directory server to communicate. This is done by using the innate encoding/decoding capabilities of the ReplicationMessages objects. This class is used by both the server and the plugin package.
- ReplicationMessage This class and the class that inherit from it contain the messages that are used for communication between the replication server and the Directory Server as well as the methods fro encoding/decoding them.

Interface Summary Interface Description Session Defines a replication session using TLS.UpdateMsgVisitor<E extends Exception> A visitor ofUpdateMsgs, in the style of the visitor design pattern. -
Class Summary Class Description AddContext This class describes the context that is attached to Add Operation.AddMsg This class is used to exchange Add operation between LDAP servers and replication servers.ByteArrayBuilder Byte array builder class encodes data into byte arrays to send messages over the replication protocol.ByteArrayScanner Byte array scanner class helps decode data from byte arrays received via messages over the replication protocol.ChangeStatusMsg This message is used by the replica to tell the replication server he is changing his status (new status field used), or by the replication server to request that the replica changes his status (requested status field used).ChangeTimeHeartbeatMsg Class that define messages sent by a replication domain (DS) to the replication server to let the RS know the DS current change time.DeleteContext This class is used to describe the context attached to a Delete Operation.DeleteMsg Object used when sending delete information to replication servers.DoneMsg This message is part of the replication protocol.EntryMsg This message is part of the replication protocol.ErrorMsg This message is part of the replication protocol.ExtendedStartMsg Added in protocol V10 to exchange additional information during handshake.HeartbeatMsg This message is sent at regular intervals by the replication server when it is sending no other messages.InitializationMsg This is an abstract class of messages of the replication protocol for message that needs to contain information about the server that send them and the destination servers to which they should be sent.InitializeRcvAckMsg This message is used by Replicas to update the send window of the peer replica.InitializeRequestMsg This message is part of the replication protocol.InitializeTargetMsg This message is part of the replication protocol.LDAPUpdateMsg Abstract class that must be extended to define a message used for sending Updates between servers.ModifyCommonMsg This class holds every common code for the modify messages (mod, moddn).ModifyContext This class describe the replication context that is attached to Modify operation.ModifyDnContext This class describe the replication context that is attached to ModifyDN operation.ModifyDNMsg Message used to send Modify DN information.ModifyMsg Message used to send Modify information.MonitorMsg The monitor message is sent by a RS to either a DS or a RS.MonitorRequestMsg This message is part of the replication protocol.OperationContext This class describe the replication context that is attached to each Operation using the SYNCHROCONTEXT key.ProtocolVersion The version utility class for the replication protocol.ReplicaOfflineMsg Class that define messages sent by a replica (DS) to the replication server (RS) to let the RS know the date at which a replica went offline.ReplicationMsg Abstract class that must be used when defining messages that can be sent for replication purpose between servers.ReplServerStartDSMsg Message sent by a replication server to a directory server in reply to the ServerStartMsg.ReplServerStartMsg Message sent by a replication server to another replication server at Startup.ReplSessionSecurity This class represents the security configuration for replication protocol sessions.ResetGenerationIdMsg This message is used by an LDAP server to communicate to the topology that the generation must be reset for the domain.ServerStartMsg This message is used by LDAP server when they first connect.StartMsg This abstract message class is the superclass for start messages used by LDAP servers and Replication servers to initiate their communications.StartSessionMsg This message is used by DS to confirm a RS he wants to connect to him (open a session).StopEncryptionMsg Internal message to signal the stop of encryption.StopMsg This message is part of the replication protocol.TopologyMsg This class defines a message that is sent: By a RS to the other RSs in the topology, containing: every DSs directly connected to the RS in the DS infos every connected RSs (including the sending RS) in the RS infos By a RS to his connected DSs, containing.UpdateMsg Abstract class that must be extended to define a message used for sending Updates between servers.WindowMsg This message is used by LDAP server or by Replication Servers to update the send window of the remote entities.WindowProbeMsg This message is used by LDAP or Replication Server that have been out of credit for a while and want to check if the remote servers is able to accept more messages. -
Enum Summary Enum Description StopMsg.StopReason The reason why the connection might be terminated. -
Exception Summary Exception Description NotSupportedOldVersionPDUException This exception should be raised by the un-serialization code of a PDU (typically the constructor code with a byte[] parameter), when the detected PDU type (deduced from the first received byte of the message) is a PDU used in an older version of the replication protocol than the current one, and we do not support translation from this old version PDU to his matching PDU in the current protocol version (if it exists).
