Constructor Detail

FCMembership

public FCMembership()

FCMembership

public FCMembership(int heartbeatInterval,
            int timeoutAfterNIntervals)

Method Detail

getNodeState

public Object getNodeState()

setNodeState

public void setNodeState(Object nodeState)

application provided serializable object which is broadcasted. Each node in the cluster maintains a list of cluster nodes and their associated nodestate

Parameters:

nodeState -

getHeartbeatInterval

public int getHeartbeatInterval()

getListener

public FCMembership.MemberShipListener getListener()

setListener

public void setListener(FCMembership.MemberShipListener listener)

setHeartbeatInterval

public void setHeartbeatInterval(int heartbeatInterval)

getTimeoutAfterNIntervals

public int getTimeoutAfterNIntervals()

setTimeoutAfterNIntervals

public void setTimeoutAfterNIntervals(int timeoutAfterNIntervals)

init

public void init()

Description copied from class: FCTopicService

override to do init and stuff

Overrides:

init in class FCTopicService

getStats

public void getStats(String topic,
            FCFutureResultHandler result)

getActiveTopics

public void getActiveTopics(FCFutureResultHandler res)

ping

public void ping(long timeSent,
        Object nodeStateObject)

getNodeInfo

public void getNodeInfo(FCFutureResultHandler res)

clusterLog

public void clusterLog(String text)

invoke

protected boolean invoke(int methodIndex,
             Method m,
             de.ruedigermoeller.serialization.FSTObjectInput in,
             Class[] types)

Description copied from class: FCTopicService

called right before decoding, return true to consume the call. If you read from the object stream, you need to consume or rewind the stream to its original position.

Overrides:

invoke in class FCTopicService

Returns:

updateActiveNodes

protected List<FCMembership.NodePingInfo> updateActiveNodes(long lastPingDelay)

getActiveNodes

public List<FCMembership.NodePingInfo> getActiveNodes()

getActiveNodes

public List<FCMembership.NodePingInfo> getActiveNodes(String subString)

getActiveNodesOrderDeterministic

public FCMembership.NodePingInfo[] getActiveNodesOrderDeterministic(String subString)

getActiveNodes

getActiveNodeAdressesOrderDeterministic

public String[] getActiveNodeAdressesOrderDeterministic(String subString)

dumpToString

public String dumpToString()

dump

public void dump()

nodeAdded

             Object nodeState)

nodeLost

public void nodeLost(String lostNode)

isDoLogClusterMessages

public boolean isDoLogClusterMessages()

setDoLogClusterMessages

public void setDoLogClusterMessages(boolean doLogClusterMessages)

if true, this node receives cluster messages and logs them to the local logger with level 'FCLog.CLUSTER_LISTENER'

Parameters:
