## Class AbstractUntypedIteratorDecorator<I,O>

- java.lang.Object
- - org.apache.commons.collections4.iterators.AbstractUntypedIteratorDecorator<I,O>

- All Implemented Interfaces:
    Iterator<O>
  Direct Known Subclasses:
    AbstractIteratorDecorator

      public abstract class AbstractUntypedIteratorDecorator<I,O>
      extends Object
      implements Iterator<O>

  Provides basic behaviour for decorating an iterator with extra functionality without committing the generic type of the Iterator implementation.

  All methods are forwarded to the decorated iterator.

  Since:
    4.0
