public class Executors
extends Object

Factory and utility methods for Executor, ExecutorService, ScheduledExecutorService, ThreadFactory, and Callable classes defined in this package. This class supports the following kinds of methods:

• Methods that create and return an ExecutorService set up with commonly useful configuration settings.
• Methods that create and return a ScheduledExecutorService set up with commonly useful configuration settings.
• Methods that create and return a "wrapped" ExecutorService, that disables reconfiguration by making implementation-specific methods inaccessible.
• Methods that create and return a ThreadFactory that sets newly created threads to a known state.
• Methods that create and return a Callable out of other closure-like forms, so they can be used in execution methods requiring Callable.

Method Summary

static Callable<Object>	callable(PrivilegedAction action) Returns a Callable object that, when called, runs the given privileged action and returns its result.
static Callable<Object>	callable(PrivilegedExceptionAction action) Returns a Callable object that, when called, runs the given privileged exception action and returns its result.
static Callable<Object>	callable(Runnable task) Returns a Callable object that, when called, runs the given task and returns null.
static <T> Callable<T>	callable(Runnable task, T result) Returns a Callable object that, when called, runs the given task and returns the given result.
static ThreadFactory	defaultThreadFactory() Returns a default thread factory used to create new threads.
static ExecutorService	newCachedThreadPool() Creates a thread pool that creates new threads as needed, but will reuse previously constructed threads when they are available.
static ExecutorService	newCachedThreadPool(ThreadFactory threadFactory) Creates a thread pool that creates new threads as needed, but will reuse previously constructed threads when they are available, and uses the provided ThreadFactory to create new threads when needed.
static ExecutorService	newFixedThreadPool(int nThreads) Creates a thread pool that reuses a fixed set of threads operating off a shared unbounded queue.
static ExecutorService	newFixedThreadPool(int nThreads, ThreadFactory threadFactory) Creates a thread pool that reuses a fixed set of threads operating off a shared unbounded queue, using the provided ThreadFactory to create new threads when needed.
static ScheduledExecutorService	newScheduledThreadPool(int corePoolSize) Creates a thread pool that can schedule commands to run after a given delay, or to execute periodically.
static ScheduledExecutorService	newScheduledThreadPool(int corePoolSize, ThreadFactory threadFactory) Creates a thread pool that can schedule commands to run after a given delay, or to execute periodically.
static ExecutorService	newSingleThreadExecutor() Creates an Executor that uses a single worker thread operating off an unbounded queue.
static ExecutorService	newSingleThreadExecutor(ThreadFactory threadFactory) Creates an Executor that uses a single worker thread operating off an unbounded queue, and uses the provided ThreadFactory to create a new thread when needed.
static ScheduledExecutorService	newSingleThreadScheduledExecutor() Creates a single-threaded executor that can schedule commands to run after a given delay, or to execute periodically.
static ScheduledExecutorService	newSingleThreadScheduledExecutor(ThreadFactory threadFactory) Creates a single-threaded executor that can schedule commands to run after a given delay, or to execute periodically.
static <T> Callable<T>	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>	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.
static ThreadFactory	privilegedThreadFactory() Returns a thread factory used to create new threads that have the same permissions as the current thread.
static ExecutorService	unconfigurableExecutorService(ExecutorService executor) Returns an object that delegates all defined ExecutorService methods to the given executor, but not any other methods that might otherwise be accessible using casts.
static ScheduledExecutorService	unconfigurableScheduledExecutorService(ScheduledExecutorService executor) Returns an object that delegates all defined ScheduledExecutorService methods to the given executor, but not any other methods that might otherwise be accessible using casts.
