Method Detail

run

public void run()

Specified by:

run in interface java.lang.Runnable

finishSession

public static void finishSession(InetAddressAndPort from,
                                 PaxosCleanupResponse response)

onJoin

public void onJoin(InetAddressAndPort 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.

beforeChange

public void beforeChange(InetAddressAndPort endpoint,
                         EndpointState currentState,
                         ApplicationState newStateKey,
                         VersionedValue newValue)

Specified by:

beforeChange in interface IEndpointStateChangeSubscriber

onChange

public void onChange(InetAddressAndPort endpoint,
                     ApplicationState state,
                     VersionedValue value)

Specified by:

onChange in interface IEndpointStateChangeSubscriber

onAlive

public void onAlive(InetAddressAndPort endpoint,
                    EndpointState state)

Specified by:

onAlive in interface IEndpointStateChangeSubscriber

onDead

public void onDead(InetAddressAndPort endpoint,
                   EndpointState state)

Specified by:

onDead in interface IEndpointStateChangeSubscriber

onRemove

public void onRemove(InetAddressAndPort endpoint)

Specified by:

onRemove in interface IEndpointStateChangeSubscriber

onRestart

public void onRestart(InetAddressAndPort endpoint,
                      EndpointState state)

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(InetAddressAndPort ep,
                    double phi)

Description copied from interface: IFailureDetectionEventListener

Convict the specified endpoint.

Specified by:

convict in interface IFailureDetectionEventListener

Parameters:

ep - endpoint to be convicted

phi - the value of phi with with ep was convicted

onFailure

public void onFailure(InetAddressAndPort from,
                      RequestFailureReason reason)

Description copied from interface: RequestCallbackWithFailure

Called when there is an exception on the remote node or timeout happens

Specified by:

onFailure in interface RequestCallback<java.lang.Void>

Specified by:

onFailure in interface RequestCallbackWithFailure<java.lang.Void>

onResponse

public void onResponse(Message<java.lang.Void> msg)

Specified by:

onResponse in interface RequestCallback<java.lang.Void>

Parameters:

msg - response received.
