Class Blocker

java.lang.Object

com.h3c.util.concurrent.Blocker

public final class Blocker
extends Object

A class that blocks the current thread until some condition or predicate is met.

This class should be used when the condition has to be evaluated and a notification is not possible; if it is possible to get a notification when the condition may change Object.wait() and Object.notify()/ Object.notifyAll() should be used instead.

If the thread does not need to be blocked, but a condition change notification is still not possible, use Waiter instead.
