Class ConditionLatch

java.lang.Object
de.aristaflow.adept2.util.locking.ConditionLatch
public class ConditionLatch extends Object
This is similar to a normal CountDownLatch but it uses a wrapped lock for synchronising as well as a new corresponding condition for signalling. This allows to have a latch that releases a lock when waiting for the latch.
