Package org.codehaus.commons.compiler.util.iterator

Class IteratorCollection<T>

  • Type Parameters:
    T - The element type of the iterator and the collection
    All Implemented Interfaces:
    java.lang.Iterable<T>, java.util.Collection<T>
    public class IteratorCollection<T>
extends java.util.AbstractCollection<T>
    A Collection that lazily reads its elements from an Iterator.

    In other words, you can call iterator() as often as you want, but the IteratorCollection will iterate over its delegate only once.
