close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface Releasable

start

public void start()

Specified by:

start in interface ZenPing

clearTemporalResponses

public void clearTemporalResponses()

Clears the list of cached ping responses.

ping

public void ping(Consumer<ZenPing.PingCollection> resultsConsumer,
 TimeValue duration)

Sends three rounds of pings notifying the specified Consumer when pinging is complete. Pings are sent after resolving configured unicast hosts to their IP address (subject to DNS caching within the JVM). A batch of pings is sent, then another batch of pings is sent at half the specified TimeValue, and then another batch of pings is sent at the specified TimeValue. The pings that are sent carry a timeout of 1.25 times the specified TimeValue. When pinging each node, a connection and handshake is performed, with a connection timeout of the specified TimeValue.

Specified by:

ping in interface ZenPing

Parameters:

resultsConsumer - the callback when pinging is complete

duration - the timeout for various components of the pings

ping

protected void ping(Consumer<ZenPing.PingCollection> resultsConsumer,
 TimeValue scheduleDuration,
 TimeValue requestDuration)

a variant of ping(Consumer, TimeValue), but allows separating the scheduling duration from the duration used for request level time outs. This is useful for testing

finishPingingRound

protected void finishPingingRound(UnicastZenPing.PingingRound pingingRound)

sendPings

protected void sendPings(TimeValue timeout,
 UnicastZenPing.PingingRound pingingRound)

submitToExecutor

protected void submitToExecutor(AbstractRunnable abstractRunnable)

getPingResponseHandler

protected TransportResponseHandler<UnicastZenPing.UnicastPingResponse> getPingResponseHandler(UnicastZenPing.PingingRound pingingRound,
 DiscoveryNode node)
