Method Detail

acquire

public void acquire()
             throws SignalAcquireException

Signal is acquired prior to processing of the signal to protect group resources being acquired from being affected by a race condition

Specified by:

acquire in interface Signal

Throws:

SignalAcquireException

release

public void release()
             throws SignalReleaseException

Signal is released after processing of the signal to bring the group resources to a state of availability

Specified by:

release in interface Signal

getMemberToken

public String getMemberToken()

returns the identity token of the member that caused this signal to be generated. For instance, in the case of a MessageSignal, this member token would be the sender. In the case of a FailureNotificationSignal, this member token would be the failed member. In the case of a JoinNotificationSignal or PlannedShutdownSignal, the member token would be the member who joined or is being gracefully shutdown, respectively.
