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.

@FunctionalInterface public interface TaskExecutor extends Executor {
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.

Params:
  • task – the Runnable to execute (never null)
Throws:
/** * Execute the given {@code task}. * <p>The call might return immediately if the implementation uses * an asynchronous execution strategy, or might block in the case * of synchronous execution. * @param task the {@code Runnable} to execute (never {@code null}) * @throws TaskRejectedException if the given task was not accepted */
