Interface TaskExecutor

All Superinterfaces:
All Known Subinterfaces:
AsyncListenableTaskExecutor, AsyncTaskExecutor, SchedulingTaskExecutor
All Known Implementing Classes:
ConcurrentTaskExecutor, ConcurrentTaskScheduler, DefaultManagedTaskExecutor, DefaultManagedTaskScheduler, SimpleAsyncTaskExecutor, SimpleThreadPoolTaskExecutor, SyncTaskExecutor, TaskExecutorAdapter, ThreadPoolTaskExecutor, ThreadPoolTaskScheduler
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface public interface TaskExecutor extends Executor
Simple task executor interface that abstracts the execution of a Runnable.

Implementations can use all sorts of different execution strategies, such as: synchronous, asynchronous, using a thread pool, and more.

Equivalent to JDK 1.5's Executor interface; extending it now in Spring 3.0, so that clients may declare a dependency on an Executor and receive any TaskExecutor implementation. This interface remains separate from the standard Executor interface mainly for backwards compatibility with JDK 1.4 in Spring 2.x.

      void execute(Runnable task)
      Execute the given task.

      The call might return immediately if the implementation uses an asynchronous execution strategy, or might block in the case of synchronous execution.

      Specified by:

      task - the Runnable to execute (never null)
