Subject [jira] [Created] (COLLECTIONS-396) New DynamicIterator class.
Date Fri, 02 Mar 2012 20:45:57 GMT
New DynamicIterator class.
--------------------------

                 Key: COLLECTIONS-396
                 URL: https://issues.apache.org/jira/browse/COLLECTIONS-396
             Project: Commons Collections
          Issue Type: New Feature
          Components: Iterator
         Environment: Java 1.5 or greater
            Reporter: Jeff Rodriguez
            Priority: Minor
         Attachments: DynamicIterator.java, DynamicIteratorTest.java

I would like to submit my DynamicIterator class for inclusion in Commons Collections.

Description from JavaDoc:

Iterates over the elements of an inner iterator provided by {@link #nextIterator()} Once the
inner iterator's {@link Iterator#hasNext()} method returns false, {@link #nextIterator()}
will be called to obtain another iterator, and so on until {@link #nextIterator()} returns
null.

The use case I had in mind for this class was the paged web service. A web service returns
a list of results, which are paginated. Once a page's results are exhausted, {@link #nextIterator()}
can go fetch the next page for iteration.

This class, and accompanying test class are my original works. I have released them into the
public domain, feel free to use the appropriate ASF license.
