Uses of Callable in java.util.concurrent

Methods in java.util.concurrent that return Callable

Modifier and Type	Method and Description
static Callable<Object>	Executors.callable(PrivilegedAction<?> action) Returns a Callable object that, when called, runs the given privileged action and returns its result.
static Callable<Object>	Executors.callable(PrivilegedExceptionAction<?> action) Returns a Callable object that, when called, runs the given privileged exception action and returns its result.
static Callable<Object>	Executors.callable(Runnable task) Returns a Callable object that, when called, runs the given task and returns null.
static <T> Callable<T>	Executors.callable(Runnable task, T result) Returns a Callable object that, when called, runs the given task and returns the given result.
static <T> Callable<T>	Executors.privilegedCallable(Callable<T> callable) Returns a Callable object that will, when called, execute the given callable under the current access control context.
static <T> Callable<T>	Executors.privilegedCallableUsingCurrentClassLoader(Callable<T> callable) Returns a Callable object that will, when called, execute the given callable under the current access control context, with the current context class loader as the context class loader.

Methods in java.util.concurrent with parameters of type Callable

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 ForkJoinTask.join(), translating any checked exceptions encountered into RuntimeException.
protected <V> RunnableScheduledFuture<V>	ScheduledThreadPoolExecutor.decorateTask(Callable<V> callable, RunnableScheduledFuture<V> task) Modifies or replaces the task used to execute a callable.
protected <T> RunnableFuture<T>	ForkJoinPool.newTaskFor(Callable<T> callable)
protected <T> RunnableFuture<T>	AbstractExecutorService.newTaskFor(Callable<T> callable) Returns a RunnableFuture for the given callable task.
static <T> Callable<T>	Executors.privilegedCallable(Callable<T> callable) Returns a Callable object that will, when called, execute the given callable under the current access control context.
static <T> Callable<T>	Executors.privilegedCallableUsingCurrentClassLoader(Callable<T> callable) Returns a Callable object that will, when called, execute the given callable under the current access control context, with the current context class loader as the context class loader.
<V> ScheduledFuture<V>	ScheduledThreadPoolExecutor.schedule(Callable<V> callable, long delay, TimeUnit unit)
<V> ScheduledFuture<V>	ScheduledExecutorService.schedule(Callable<V> callable, long delay, TimeUnit unit) Creates and executes a ScheduledFuture that becomes enabled after the given delay.
<T> Future<T>	ScheduledThreadPoolExecutor.submit(Callable<T> task)
<T> ForkJoinTask<T>	ForkJoinPool.submit(Callable<T> task)
<T> Future<T>	AbstractExecutorService.submit(Callable<T> task)
<T> Future<T>	ExecutorService.submit(Callable<T> task) Submits a value-returning task for execution and returns a Future representing the pending results of the task.
Future<V>	ExecutorCompletionService.submit(Callable<V> task)
Future<V>	CompletionService.submit(Callable<V> task) Submits a value-returning task for execution and returns a Future representing the pending results of the task.

Method parameters in java.util.concurrent with type arguments of type Callable

Modifier and Type	Method and Description
<T> List<Future<T>>	ForkJoinPool.invokeAll(Collection<? extends Callable<T>> tasks)
<T> List<Future<T>>	AbstractExecutorService.invokeAll(Collection<? extends Callable<T>> tasks)
<T> List<Future<T>>	ExecutorService.invokeAll(Collection<? extends Callable<T>> tasks) Executes the given tasks, returning a list of Futures holding their status and results when all complete.
<T> List<Future<T>>	AbstractExecutorService.invokeAll(Collection<? extends Callable<T>> tasks, long timeout, TimeUnit unit)
<T> List<Future<T>>	ExecutorService.invokeAll(Collection<? extends Callable<T>> tasks, long timeout, TimeUnit unit) Executes the given tasks, returning a list of Futures holding their status and results when all complete or the timeout expires, whichever happens first.
<T> T	AbstractExecutorService.invokeAny(Collection<? extends Callable<T>> tasks)
<T> T	ExecutorService.invokeAny(Collection<? extends Callable<T>> tasks) Executes the given tasks, returning the result of one that has completed successfully (i.e., without throwing an exception), if any do.
<T> T	AbstractExecutorService.invokeAny(Collection<? extends Callable<T>> tasks, long timeout, TimeUnit unit)
<T> T	ExecutorService.invokeAny(Collection<? extends Callable<T>> tasks, long timeout, TimeUnit unit) Executes the given tasks, returning the result of one that has completed successfully (i.e., without throwing an exception), if any do before the given timeout elapses.

Constructor and Description

FutureTask(Callable<V> callable)
Creates a FutureTask that will, upon running, execute the given Callable.
