public interface WithMutexes
interface which allows multiple callers to co-operate using named mutexes, inspectably, and containing implementation as inner class
MutexSupport is a common implementation of this. mixin code frequently delegates to this, as shown in the test case's WithMutexesTest.SampleWithMutexesDelegatingMixin class
Method Summary | |
---|---|
void
|
acquireMutex(java.lang.String mutexId, java.lang.String description)
acquires a mutex, if available, otherwise blocks on its becoming available; caller must release after use |
boolean
|
hasMutex(java.lang.String mutexId)
returns true if the calling thread has the mutex with the given ID |
void
|
releaseMutex(java.lang.String mutexId)
releases a mutex, triggering another thread to use it or cleaning it up if no one else is waiting; this should only be called by the mutex owner (thread) |
boolean
|
tryAcquireMutex(java.lang.String mutexId, java.lang.String description)
acquires a mutex and returns true, if available; otherwise immediately returns false; caller must release after use if this returns true |
