ReadWriteLock

java.util.concurrent.locks

---

Java 5.0

This interface represents a pair of Lock objects with special locking behavior that is useful for concurrent algorithms in which reader threads frequently access a data structure and writer threads only infrequently modify the structure. The Lock returned by readLock( ) may be locked by multiple threads at the same time as long as no thread has the writeLock( ) locked. See ReentrantReadWriteLock for a concrete implementation with implementation-specific locking details.

 public interface  ReadWriteLock  {  // Public Instance Methods  Lock  readLock  ( );        Lock  writeLock  ( );   }
