Class FindAllIterator<T>

java.lang.Object
  net.sf.jga.util.FindAllIterator<T>

All Implemented Interfaces:

java.lang.Iterable<java.util.Iterator<? extends T>>, java.util.Iterator<java.util.Iterator<? extends T>>

public class FindAllIterator<T>
extends java.lang.Object
implements java.lang.Iterable<java.util.Iterator<? extends T>>, java.util.Iterator<java.util.Iterator<? extends T>>

Iterator that applies one of the FindX functors as many times as possible. Formally, this iterator uses a functor that takes one iterator and returns an iterator, and repeatedly applies it to a given iterator until the result iterator's hasNext() method is false.
