Class CachingIterator

java.lang.Object
  com.generationjava.collections.CachingIterator

All Implemented Interfaces:

Iterator, ResetableIterator

public class CachingIterator

extends Object

implements ResetableIterator

A piping Iterator which caches all objects that pass through it. When reset is called, it returns to the start of its cache. This however only allows for one version of the iterator at a time to be used. It gets used again and again. The alternative is to use the static cache method, or the iterate method. Both of which may be used to get a new Iterator over the same data.
