FeederReplicaHandshake

public FeederReplicaHandshake(RepNode repNode,
                              Feeder feeder,
                              NamedChannel namedChannel)

An instance of this class is created with each new handshake preceding the setting up of a connection.

Parameters:

repNode - the replication node

feeder - the feeder instance

namedChannel - the channel to be used for the handshake

Method Detail

getReplicaNameIdPair

public NameIdPair getReplicaNameIdPair()

Returns the replica node ID. The returned value is only valid after the handshake has been executed.

Returns:

the replica node name id pair

getStreamLogVersion

public int getStreamLogVersion()

Return the negotiated log version that will be used for the HA stream between the feeder and the replica.

setTestLogVersion

public static void setTestLogVersion(int testLogVersion)

getReplicaJEVersion

public JEVersion getReplicaJEVersion()

Returns the JE version supported by the replica, or null if the value is not yet known. This method should only be called after the execute() method has returned successfully.

Returns:

the replica's JE version or null

getReplicaNode

public RepNodeImpl getReplicaNode()

Returns a RepNodeImpl that represents the replica for a successful handshake. This method should only be called after the execute() method has returned successfully, and will throw IllegalStateException otherwise.

Returns:

the replica node

Throws:

IllegalStateException - if the handshake did not complete
