Example text

However, a synchronized statement nested within another statement synchronized on the same object causes no problems. This is because the Java Virtual Machine 18 Java Thin-Client Programming checks the identity of the thread that holds the monitor before it applies a lock. This is useful because it allows you to call a synchronized method from within another synchronized method. However, using synchronized is subject to errors when other objects come into play. Suppose one thread is executing the following code.

Condition variables address exactly this issue. Figure 10 on page 24 shows the implementation of a condition variable. Note that condition variables require a mutex as a member, and it is that mutex that is used to implement critical sections. This allows any object to be accessed in a critical section without the need to synchronize on the object itself. Using condition variables allows for great flexibility and control, at the cost of greater complexity for the application developer. In addition to the mutex, there is a count of waiting threads, and an object that is used to call wait() and notify().

The instance variables include a mutex and two condition variables, corresponding to the conditions that is safe to read or safe to write. There is also a count of the currently active readers, and the current writer plus the currently waiting writers. If the object is locked for writing the boolean activeWriter will be set to true. Note that mutex mux does not exist to protect the external object, but to protect the instance variables of the RWMutex. An instance of RWMutex will itself be used to guard the external object.
