Class FilterListIterator

  • All Implemented Interfaces:
    java.util.Iterator, java.util.ListIterator
    @Deprecated(since="2021-04-30")
public class FilterListIterator
extends java.lang.Object
implements java.util.ListIterator
    Deprecated.
    Commons Collections 3 is in maintenance mode. Commons Collections 4 should be used instead.
    Decorates another ListIterator using a predicate to filter elements.

    This iterator decorates the underlying iterator, only allowing through those elements that match the specified Predicate.

    Since:
    Commons Collections 2.0
