All Implemented Interfaces:

public class MutexSupport
Method Summary
void acquireMutex(java.lang.String mutexId, java.lang.String description)

void cleanup()

void cleanupMutex(java.lang.String mutexId)

forces deletion of the given mutex if it is unused; normally not required as is done automatically on close (but possibly needed where there are cancelations and risk of memory leaks)
java.util.Map getAllSemaphores()

Returns the semaphores in use at the time the method is called, for inspection purposes (and testing).

Method Detail

acquireMutex

public void acquireMutex(String mutexId, String description) throws InterruptedException {
public void acquireMutex(java.lang.String mutexId, java.lang.String description)

cleanup

public void cleanup()

cleanupMutex

public void cleanupMutex(java.lang.String mutexId)
forces deletion of the given mutex if it is unused; normally not required as is done automatically on close (but possibly needed where there are cancelations and risk of memory leaks)

getAllSemaphores

public java.util.Map getAllSemaphores()
Returns the semaphores in use at the time the method is called, for inspection purposes (and testing). The semaphores used by this class may change over time so callers are strongly discouraged from manipulating the semaphore objects themselves.

getSemaphore

protected SemaphoreWithOwners getSemaphore(java.lang.String mutexId)

getSemaphore

hasMutex

public synchronized boolean hasMutex(String mutexId) {

releaseMutex

public synchronized void releaseMutex(String mutexId) {
public void releaseMutex(java.lang.String mutexId)

toString

public synchronized String toString() {
public java.lang.String toString()

tryAcquireMutex

public boolean tryAcquireMutex(String mutexId, String description) {
public boolean tryAcquireMutex(java.lang.String mutexId, java.lang.String description)
