class AsyncLatch extends AnyRef

A construct providing latched, asynchronous execution of side-effecting functions. com.twitter.finagle.util.AsyncLatch#await does not block, but the execution of functions passed to it may be delayed. That is, because the latch guarantees serial, non-concurrent execution, functions passed to await may have to wait until both of the following conditions are met:

1. No other functions are being executed 2. The latch's count is zero

Thus, calling com.twitter.finagle.util.AsyncLatch#incr will cause subsequent functions passed to com.twitter.finagle.util.AsyncLatch#await to be delayed until the count is decremented to zero. Once the count is zero, functions are executed in the order that they are provided to await.

  7. def decr(): Int

    Decrement the latch.

    Decrement the latch. If the latch's count reaches zero, awaiting computations are executed serially.

    returns

    the latch's count after being decremented

  14. def incr(): Int

    Increment the latch.

    Increment the latch. Computations passed to await will not be executed until the latch's count returns to zero.

    returns

    the latch's count after being incremented
