Interface TaskExecutor

All Superinterfaces:

Executor

All Known Subinterfaces:

AsyncListenableTaskExecutor, AsyncTaskExecutor

All Known Implementing Classes:

SimpleAsyncTaskExecutor, SyncTaskExecutor, TaskExecutorAdapter

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.

Since:

2.0
