java.util.concurrent
class AbstractExecutorService
- All Implemented Interfaces:
- ExecutorService
- Direct Known Subclasses:
- ThreadPoolExecutor
public abstract class AbstractExecutorService
extends Object
implements ExecutorService
Provides default implementations of {@link ExecutorService}
execution methods. This class implements the submit,
invokeAny and invokeAll methods using a
{@link RunnableFuture} returned by newTaskFor, which defaults
to the {@link FutureTask} class provided in this package. For example,
the implementation of submit(Runnable) creates an
associated RunnableFuture that is executed and
returned. Subclasses may override the newTaskFor methods
to return RunnableFuture implementations other than
FutureTask.
Extension example. Here is a sketch of a class
that customizes {@link ThreadPoolExecutor} to use
a CustomTask class instead of the default FutureTask:
public class CustomThreadPoolExecutor extends ThreadPoolExecutor {
static class CustomTask<V> implements RunnableFuture<V> {...}
protected <V> RunnableFuture<V> newTaskFor(Callable<V> c) {
return new CustomTask<V>(c);
}
protected <V> RunnableFuture<V> newTaskFor(Runnable r, V v) {
return new CustomTask<V>(r, v);
}
// ... add constructors, etc.
}

newTaskFor
protected RunnableFuture newTaskFor(Callable callable)
-
Returns a RunnableFuture for the given callable task.
- Parameters:
callable
- the callable task being wrapped
- Returns:
- a RunnableFuture which when run will call the
underlying callable and which, as a Future, will yield
the callable's result as its result and provide for
cancellation of the underlying task.
newTaskFor
protected RunnableFuture newTaskFor(Runnable runnable,
Object value)
-
Returns a RunnableFuture for the given runnable and default
value.
- Parameters:
runnable
- the runnable task being wrapped
value
- the default value for the returned future
- Returns:
- a RunnableFuture which when run will run the
underlying runnable and which, as a Future, will yield
the given value as its result and provide for cancellation of
the underlying task.

-
- Parameters:
task
submit
public Future submit(Runnable task)
-
- Parameters:
