IdReadWriteLock (Apache HBase 1.4.11 API)

java.lang.Object
- org.apache.hadoop.hbase.util.IdReadWriteLock

@InterfaceAudience.Private
public class IdReadWriteLock
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()
