Class FitnessEvaluationWorker

java.lang.Object
  org.uncommons.watchmaker.framework.FitnessEvaluationWorker

public class FitnessEvaluationWorker
extends Object

This is the class that actually runs the fitness evaluation tasks created by a EvolutionEngine. This responsibility is abstracted away from the evolution engine to permit the possibility of creating multiple instances across several machines, all fed by a single shared work queue, using Terracotta (http://www.terracotta.org) or similar.

Method Detail

submit

public <T> Future<EvaluatedCandidate<T>> submit(org.uncommons.watchmaker.framework.FitnessEvalutationTask<T> task)

main

public static void main(String[] args)

Entry-point for running this class standalone, as an additional node for fitness evaluations. If this method is invoked without using Terracotta (or similar) to share the work queue, the program will do nothing.

Parameters:

args - Program arguments, should be empty.

finalize

protected void finalize()
                 throws Throwable

A FitnessWorker cannot be garbage-collected if its thread pool has not been shutdown. This method, invoked on garabage collection (or maybe not at all), shuts down the thread pool so that the threads can be released.

Overrides:

finalize in class Object

Throws:

Throwable - Any exception or error that occurs during finalisation.
