Class ReadWriteLock

java.lang.Object
com.aquima.interactions.foundation.utility.ReadWriteLock
public class ReadWriteLock extends Object
Read-write mutex implementation that can be used to allow concurrent reads, but single threaded writes.

This implementation of ReadWriteLock will give preference to the waiting writer threads over the readers, through the waitingWriters variable. That means if we have two threads waiting to acquire the lock, the one waiting for write lock will get the lock first.
