RCountDownLatchRx (Redisson 3.16.1 API)乐学网一站式学习平台

All Superinterfaces:

RObjectRx
```
public interface RCountDownLatchRx
extends RObjectRx
```
RxJava2 interface of Redis based CountDownLatch It has an advantage over CountDownLatch -- count can be set via trySetCount(long) method.

- Method Detail
  - await
```
io.reactivex.rxjava3.core.Completable await()
```
    Waits until counter reach zero.
    
    Returns:
    
    void
  - await
```
io.reactivex.rxjava3.core.Single<Boolean> await(long waitTime,
                                                TimeUnit unit)
```
    Waits until counter reach zero or up to defined timeout.
    
    Parameters:
    
    waitTime - the maximum time to wait
    
    unit - the time unit
    
    Returns:
    
    true if the count reached zero and false if timeout reached before the count reached zero
  - countDown
```
io.reactivex.rxjava3.core.Completable countDown()
```
    Decrements the counter of the latch. Notifies all waiting threads when count reaches zero.
    
    Returns:
    
    void
  - getCount
```
io.reactivex.rxjava3.core.Single<Long> getCount()
```
    Returns value of current count.
    
    Returns:
    
    the current count
  - trySetCount
```
io.reactivex.rxjava3.core.Single<Boolean> trySetCount(long count)
```
    Sets new count value only if previous count already has reached zero or is not set at all.
    
    Parameters:
    
    count - - number of times countDown must be invoked before threads can pass through await
    
    Returns:
    
    true if new count setted false if previous count has not reached zero
