Class Mutex.Privileged

java.lang.Object

org.openide.util.Mutex.Privileged

Enclosing class:

Mutex

public static final class Mutex.Privileged
extends Object

Provides access to Mutex's internal methods. This class can be used when one wants to avoid creating a bunch of Runnables. Instead,

 try {
     enterXAccess ();
     yourCustomMethod ();
 } finally {
     exitXAccess ();
 }
 

can be used. You must, however, control the related Mutex, i.e. you must be creator of the Mutex.
