[jira] [Created] (LANG-1275) Add a tryAcquire() method to TimedSemaphore

Oliver Heger created LANG-1275:
----------------------------------

             Summary: Add a tryAcquire() method to TimedSemaphore
                 Key: LANG-1275
                 URL: https://issues.apache.org/jira/browse/LANG-1275
             Project: Commons Lang
          Issue Type: Improvement
          Components: lang.concurrent.*
    Affects Versions: 3.4
            Reporter: Oliver Heger


In order to support non-blocking use cases and be more in-line with Java's {{Semaphore}} class, {{TimedSemaphore}} should support a _tryAcquire()_ method:

{code}
public boolean tryAcquire();
{code}

The method checks whether another permit can be acquired. If so, it acquires the permit and returns *true*. Otherwise, it returns *false* without blocking the calling thread.
