Scala example source code file (

This example Scala source code file ( is included in my "Source Code Warehouse" project. The intent of this project is to help you more easily find Scala source code examples by using tags.

All credit for the original source code belongs to; I'm just trying to make examples easier to find. (For my Scala work, see my Scala examples and tutorials.)

Scala tags/keywords

actor, rejectedexecutionhandler, thread, threadpool, threadpoolexecutor

The Scala example source code

 * Written by Doug Lea with assistance from members of JCP JSR-166
 * Expert Group and released to the public domain, as explained at

package scala.actors.threadpool;

 * A handler for tasks that cannot be executed by a {@link ThreadPoolExecutor}.
 * @since 1.5
 * @author Doug Lea
public interface RejectedExecutionHandler {

     * Method that may be invoked by a {@link ThreadPoolExecutor} when
     * {@link ThreadPoolExecutor#execute execute} cannot accept a
     * task.  This may occur when no more threads or queue slots are
     * available because their bounds would be exceeded, or upon
     * shutdown of the Executor.
     * <p>In the absence of other alternatives, the method may throw
     * an unchecked {@link RejectedExecutionException}, which will be
     * propagated to the caller of {@code execute}.
     * @param r the runnable task requested to be executed
     * @param executor the executor attempting to execute this task
     * @throws RejectedExecutionException if there is no remedy

    void rejectedExecution(Runnable r, ThreadPoolExecutor executor);
