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, thread, threadfactory, threadpool

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;

 * An object that creates new threads on demand.  Using thread factories
 * removes hardwiring of calls to {@link Thread#Thread(Runnable) new Thread},
 * enabling applications to use special thread subclasses, priorities, etc.
 * <p>
 * The simplest implementation of this interface is just:
 * <pre>
 * class SimpleThreadFactory implements ThreadFactory {
 *   public Thread newThread(Runnable r) {
 *     return new Thread(r);
 *   }
 * }
 * </pre>
 * The {@link Executors#defaultThreadFactory} method provides a more
 * useful simple implementation, that sets the created thread context
 * to known values before returning it.
 * @since 1.5
 * @author Doug Lea
public interface ThreadFactory {

     * Constructs a new {@code Thread}.  Implementations may also initialize
     * priority, name, daemon status, {@code ThreadGroup}, etc.
     * @param r a runnable to be executed by new thread instance
     * @return constructed thread, or {@code null} if the request to
     *         create a thread is rejected
    Thread newThread(Runnable r);
