PausedExecutorService (framework 4.9 API)

java.lang.Object
- java.util.concurrent.AbstractExecutorService
- - org.robolectric.android.util.concurrent.PausedExecutorService

All Implemented Interfaces:

Executor, ExecutorService
```
@Beta
public class PausedExecutorService
extends AbstractExecutorService
```
Executor service that queues any posted tasks. Users must explicitly call runAll() to execute all pending tasks. Intended to be a replacement for RoboExecutorService when using LooperMode.Mode.PAUSED. Unlike RoboExecutorService, will execute tasks on a background thread. This is useful to test Android code that enforces it runs off the main thread. NOTE: Beta API, subject to change.

Method Detail

runAll
```
public int runAll()
```
Execute all posted tasks and block until they are complete.

Returns:

the number of tasks executed

runNext
```
public boolean runNext()
```
Executes the next queued task. Will be ignored if called from the executor service thread to prevent deadlocks.

Returns:

true if task was run, false if queue was empty

hasQueuedTasks
```
public boolean hasQueuedTasks()
```
Returns:

true if there are queued pending tasks

shutdown
```
public void shutdown()
```

shutdownNow
```
public List<Runnable> shutdownNow()
```

isShutdown
```
public boolean isShutdown()
```

isTerminated
```
public boolean isTerminated()
```
