AbstractExecutorService


AbstractExecutorService java.util.concurrent

Java 5.0

This abstract class implements the submit( ) , invokeAll( ) , and invokeAny( ) methods of the ExecutorService interface. It does not implement the ExecutorService shutdown methods or the crucial execute( ) method for asynchronous execution of Runnable tasks .

The methods implemented by AbstractExecutorService wrap the submitted Callable or Runnable task in a FutureTask object. FutureTask implements Runnable and Future , which are first passed to the abstract execute( ) method to be run asynchronously and then returned to the caller.

See ThreadPoolExecutor for a concrete implementation, and see Executors for convenient ExecutorService factory methods.
