Summary: Fairness setting in TimedSemaphore
Key: LANG-1790
URL: https://issues.apache.org/jira/browse/LANG-1790
Project: Commons Lang
Issue Type: Improvement
Components: lang.concurrent.*
Reporter: Mert Kirpici
The {{TimedSemaphore}} structure javadocs do not mention anything about
fairness.
If this is something that the current implementatio does not provide, the
{{TimedSemaphore}} structure could benefit from a _fairness_ setting like the
{{java.util.concurrent.Semaphore}} does, which will queue up the threads that
are blocked by the {{.acquire()}} call and when the timer expires, they will be
permitted access to the shared resource in a FIFO fashion.
A possible implementation could be like this in the constructor:
{{TimedSemaphore(long timePeriod, TimeUnit timeUnit, int limit, boolean fair)}}
