Class IteratorChain

java.lang.Object
  com.phoenixst.collections.IteratorChain

All Implemented Interfaces:

Iterator

public class IteratorChain
extends Object
implements Iterator

A chain of Iterators. The one in Jakarta commons-collections doesn't work.

This is similar to the class of the same name in Jakarta Commons-Collections 3.0. This implementation is missing all of the locking and safeguards of the other one. This implementation fixes a bug in version 2.1 where hasNext() would return false if the first iterator was empty, but subsequent ones were not.

1.0
