org.apache.flink.core.testutils.MultiShotLatch

public final class MultiShotLatch
extends Object

Latch for synchronizing parts of code in tests. In contrast to OneShotLatch this will reset the state once await() returns.

A part of the code that should only run after other code calls await(). The call will only return once the other part is finished and calls trigger().
