## Class LocalTaskQueueTestConfig.TaskCountDownLatch

- java.lang.Object
- - java.util.concurrent.CountDownLatch
  - - com.google.appengine.tools.development.testing.LocalTaskQueueTestConfig.TaskCountDownLatch

- Enclosing class:
    LocalTaskQueueTestConfig

      public static final class LocalTaskQueueTestConfig.TaskCountDownLatch
      extends java.util.concurrent.CountDownLatch

  A `CountDownLatch` extension that can be reset. Pass an instance of this class to `LocalTaskQueueTestConfig#setTaskExecutionLatch)` when you need to reuse the latch within or across tests. Only one thread at a time should ever call any of the `await()` or `reset()` methods.
