@Private public abstract class IdReadWriteLock<T> extends Object
Allows multiple concurrent clients to lock on a numeric id with ReentrantReadWriteLock. The intended usage for read lock is as follows: 
 ReentrantReadWriteLock lock = idReadWriteLock.getLock(id);
 try {
   lock.readLock().lock();
   // User code.
 } finally {
   lock.readLock().unlock();
 }
For write lock, use lock.writeLock()
