Class NonBatchingQueue<E>

java.lang.Object
  org.mentaqueue.NonBatchingQueue<E>

Type Parameters:

E -

All Implemented Interfaces:

Iterable<E>, Collection<E>, Queue<E>

public class NonBatchingQueue<E>
extends Object
implements Queue<E>

A non-batching queue wrapper that takes a BatchingQueue and makes it non-batching by implementing only the poll() and offer() methods. Since it implements java.util.Queue you can use this wrapper as a replacement of the standard Java queue implementations. However you should keep in mind that batching is one of the things that make MentaQueue fast, so a non-batching queue will be many times slower. It is highly recommended that you refactor your code to use the BatchingQueue interface because the performance gains are much larger.
