Class ViewHierarchyMutex

java.lang.Object
  org.netbeans.editor.view.spi.ViewHierarchyMutex

public class ViewHierarchyMutex
extends Object
extends Object

Mutex that allows only one thread to proceed other threads must wait until the ONE finishes.
The thread that "holds" the mutex (has the mutex access granted) may reenter the mutex any number of times (just increasing a "depth" of the locking).
If the priority thread enters waiting the mutex then it will get serviced first once the current thread leaves the mutex.
