package org.springframework.core.task;
import java.util.concurrent.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.
