Class UnboundedPipeLink<T>

java.lang.Object
  jconch.pipeline.PipeLink<T>
      jconch.pipeline.impl.UnboundedPipeLink<T>

public class UnboundedPipeLink<T>
extends PipeLink<T>

An unbounded link in the pipeline. This is a very fast implementation of a link, but allows potentially unlimited elements to build up, which can be counter-productive to the multithreaded approach.

UnboundedPipeLink()
Creates a new intance of UnboundedPipeLink.

Method Summary

int	getRemainingCapacity() Have to override this because LinkedBlockingQueue.remainingCapacity() doesn't work as expected -- apparently an unbounded queue runs low on space after you insert elements.

Constructor Detail

UnboundedPipeLink

public UnboundedPipeLink()

Creates a new intance of UnboundedPipeLink.

Method Detail

getRemainingCapacity

public int getRemainingCapacity()

Have to override this because LinkedBlockingQueue.remainingCapacity() doesn't work as expected -- apparently an unbounded queue runs low on space after you insert elements. Provides an estimate of the number of elements the queue could additionally hold.

Overrides:

getRemainingCapacity in class PipeLink<T>

Returns:

An estimate of the capcity of the queue, or Integer.MAX_VALUE if it is unbounded.
