protected AbstractStreamSession(java.lang.String table,
                                Pair<java.net.InetAddress,java.lang.Long> context,
                                IStreamCallback callback)

Method Detail

getSessionId

public long getSessionId()

getHost

public java.net.InetAddress getHost()

close

public void close(boolean success)

closeInternal

protected abstract void closeInternal(boolean success)

onJoin

public void onJoin(java.net.InetAddress endpoint,
                   EndpointState epState)

Description copied from interface: IEndpointStateChangeSubscriber

Use to inform interested parties about the change in the state for specified endpoint

Specified by:

onJoin in interface IEndpointStateChangeSubscriber

Parameters:

endpoint - endpoint for which the state change occurred.

epState - state that actually changed for the above endpoint.

onChange

public void onChange(java.net.InetAddress endpoint,
                     ApplicationState state,
                     VersionedValue value)

Specified by:

onChange in interface IEndpointStateChangeSubscriber

onAlive

public void onAlive(java.net.InetAddress endpoint,
                    EndpointState state)

Specified by:

onAlive in interface IEndpointStateChangeSubscriber

onDead

public void onDead(java.net.InetAddress endpoint,
                   EndpointState state)

Specified by:

onDead in interface IEndpointStateChangeSubscriber

onRemove

public void onRemove(java.net.InetAddress endpoint)

Specified by:

onRemove in interface IEndpointStateChangeSubscriber

onRestart

public void onRestart(java.net.InetAddress endpoint,
                      EndpointState epState)

Description copied from interface: IEndpointStateChangeSubscriber

Called whenever a node is restarted. Note that there is no guarantee when that happens that the node was previously marked down. It will have only if state.isAlive() == false as state is from before the restarted node is marked up.

Specified by:

onRestart in interface IEndpointStateChangeSubscriber

convict

public void convict(java.net.InetAddress endpoint,
                    double phi)

Description copied from interface: IFailureDetectionEventListener

Convict the specified endpoint.

Specified by:

convict in interface IFailureDetectionEventListener

Parameters:

endpoint - endpoint to be convicted

phi - the value of phi with with ep was convicted
