This * interface provides a way of decoupling task submission from the * mechanics of how each task will be run, including details of thread * use, scheduling, etc. An {@code Executor} is normally used * instead of explicitly creating threads. For example, rather than * invoking {@code new Thread(new(RunnableTask())).start()} for each * of a set of tasks, you might use: * * <pre> * Executor executor = <em>anExecutor; * executor.execute(new RunnableTask1()); * executor.execute(new RunnableTask2()); * ... * </pre> * * However, the {@code Executor} interface does not strictly * require that execution be asynchronous. In the simplest case, an * executor can run the submitted task immediately in the caller's * thread: * * <pre> {@code * class DirectExecutor implements Executor { * public void execute(Runnable r) { * r.run(); * } * }}</pre> * * More typically, tasks are executed in some thread other * than the caller's thread. The executor below spawns a new thread * for each task. * * <pre> {@code * class ThreadPerTaskExecutor implements Executor { * public void execute(Runnable r) { * new Thread(r).start(); * } * }}</pre> * * Many {@code Executor} implementations impose some sort of * limitation on how and when tasks are scheduled. The executor below * serializes the submission of tasks to a second executor, * illustrating a composite executor. * * <pre> {@code * class SerialExecutor implements Executor { * final Queue<Runnable> tasks = new ArrayDeque Other Java examples (source code examples)Here is a short list of links related to this Java Executor.java source code file: |
