Method Detail

acquire

public void acquire()
             throws com.sun.enterprise.ee.cms.core.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 com.sun.enterprise.ee.cms.core.Signal

Throws:

com.sun.enterprise.ee.cms.core.SignalAcquireException - Exception when unable to aquire the signal

release

public void release()
