Class RWLock  

java.lang.Object
  marauroa.RWLock

---

public class RWLock

extends java.lang.Object

This class is a Reader/Writters lock A Reader Writer Lock is a synchronization mechanism allowing access to data. It allows multiple threads to read the data simultaneously, but only one thread at a time to update it. While a thread is updating, no other thread can read the data. The name is misleading. It may cause you to think there are two locks; in reality there is a single lock that restricts both reading and writing.
