|---|---|
| java.util.concurrent | 
 Utility classes commonly useful in concurrent programming. 
 | 
| Modifier and Type | Class and Description | 
|---|---|
class  | 
CountedCompleter<T>
A  
ForkJoinTask with a completion action performed when
 triggered and there are no remaining pending actions. | 
class  | 
RecursiveAction
A recursive resultless  
ForkJoinTask. | 
class  | 
RecursiveTask<V>
A recursive result-bearing  
ForkJoinTask. | 
| Modifier and Type | Method and Description | 
|---|---|
static <T extends ForkJoinTask<?>> | 
ForkJoinTask.invokeAll(Collection<T> tasks)
Forks all tasks in the specified collection, returning when
  
isDone holds for each task or an (unchecked) exception
 is encountered, in which case the exception is rethrown. | 
| Modifier and Type | Method and Description | 
|---|---|
static <T> ForkJoinTask<T> | 
ForkJoinTask.adapt(Callable<? extends T> callable)
Returns a new  
ForkJoinTask that performs the call
 method of the given Callable as its action, and returns
 its result upon join(), translating any checked exceptions
 encountered into RuntimeException. | 
static ForkJoinTask<?> | 
ForkJoinTask.adapt(Runnable runnable)
Returns a new  
ForkJoinTask that performs the run
 method of the given Runnable as its action, and returns
 a null result upon join(). | 
static <T> ForkJoinTask<T> | 
ForkJoinTask.adapt(Runnable runnable,
     T result)
Returns a new  
ForkJoinTask that performs the run
 method of the given Runnable as its action, and returns
 the given result upon join(). | 
ForkJoinTask<V> | 
ForkJoinTask.fork()
Arranges to asynchronously execute this task in the pool the
 current task is running in, if applicable, or using the  
ForkJoinPool.commonPool() if not inForkJoinPool(). | 
protected static ForkJoinTask<?> | 
ForkJoinTask.peekNextLocalTask()
Returns, but does not unschedule or execute, a task queued by
 the current thread but not yet executed, if one is immediately
 available. 
 | 
protected static ForkJoinTask<?> | 
ForkJoinTask.pollNextLocalTask()
Unschedules and returns, without executing, the next task
 queued by the current thread but not yet executed, if the
 current thread is operating in a ForkJoinPool. 
 | 
protected ForkJoinTask<?> | 
ForkJoinPool.pollSubmission()
Removes and returns the next unexecuted submission if one is
 available. 
 | 
protected static ForkJoinTask<?> | 
ForkJoinTask.pollTask()
If the current thread is operating in a ForkJoinPool,
 unschedules and returns, without executing, the next task
 queued by the current thread but not yet executed, if one is
 available, or if not available, a task that was forked by some
 other thread, if available. 
 | 
<T> ForkJoinTask<T> | 
ForkJoinPool.submit(Callable<T> task)  | 
<T> ForkJoinTask<T> | 
ForkJoinPool.submit(ForkJoinTask<T> task)
Submits a ForkJoinTask for execution. 
 | 
ForkJoinTask<?> | 
ForkJoinPool.submit(Runnable task)  | 
<T> ForkJoinTask<T> | 
ForkJoinPool.submit(Runnable task,
      T result)  | 
| Modifier and Type | Method and Description | 
|---|---|
void | 
ForkJoinPool.execute(ForkJoinTask<?> task)
Arranges for (asynchronous) execution of the given task. 
 | 
<T> T | 
ForkJoinPool.invoke(ForkJoinTask<T> task)
Performs the given task, returning its result upon completion. 
 | 
static void | 
ForkJoinTask.invokeAll(ForkJoinTask<?>... tasks)
Forks the given tasks, returning when  
isDone holds for
 each task or an (unchecked) exception is encountered, in which
 case the exception is rethrown. | 
static void | 
ForkJoinTask.invokeAll(ForkJoinTask<?> t1,
         ForkJoinTask<?> t2)
Forks the given tasks, returning when  
isDone holds for
 each task or an (unchecked) exception is encountered, in which
 case the exception is rethrown. | 
static void | 
ForkJoinTask.invokeAll(ForkJoinTask<?> t1,
         ForkJoinTask<?> t2)
Forks the given tasks, returning when  
isDone holds for
 each task or an (unchecked) exception is encountered, in which
 case the exception is rethrown. | 
<T> ForkJoinTask<T> | 
ForkJoinPool.submit(ForkJoinTask<T> task)
Submits a ForkJoinTask for execution. 
 | 
| Modifier and Type | Method and Description | 
|---|---|
protected int | 
ForkJoinPool.drainTasksTo(Collection<? super ForkJoinTask<?>> c)
Removes all available unexecuted submitted and forked tasks
 from scheduling queues and adds them to the given collection,
 without altering their execution status.
