Examples of org.apache.commons.collections.ResettableListIterator

org.apache.commons.collections.ResettableListIterator
Defines a list iterator that can be reset back to an initial state.
This interface allows an iterator to be repeatedly reused. @since Commons Collections 3.0 @version $Revision: 1.4 $ $Date: 2004/02/18 01:15:42 $ @author Stephen Colebourne
