## Uses of Interface
java.util.concurrent.Callable

Packages that use Callable
java.util.concurrent | Utility classes commonly useful in concurrent programming.

Uses of Callable in java.util.concurrent

Methods in java.util.concurrent that return Callable
`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
`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> 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.
`
`<T> Future<T>`
` | `AbstractExecutorService.submit(Callable<T> 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
`
`<T> List<Future<T>>`
` | `ExecutorService.invokeAll(Collection<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<Callable<T>> tasks)`
`
`<T> List<Future<T>>`
` | `ExecutorService.invokeAll(Collection<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> List<Future<T>>`
` | `AbstractExecutorService.invokeAll(Collection<Callable<T>> tasks, long timeout, TimeUnit unit)`
`
`<T> T`
` | `ExecutorService.invokeAny(Collection<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<Callable<T>> tasks)`
`
`<T> T`
` | `ExecutorService.invokeAny(Collection<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.
`
`<T> T`
` | `AbstractExecutorService.invokeAny(Collection<Callable<T>> tasks, long timeout, TimeUnit unit)`

Constructors in java.util.concurrent with parameters of type Callable
`FutureTask(Callable<V> callable)` Creates a `FutureTask` that will upon running, execute the given `Callable`.
