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.
