# Class AbstractUntypedIteratorDecorator<I,O>

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

Type Parameters:
  `I` - The type of the iterator being decorated.
  `O` - The type of elements returned by this iterator.

All Implemented Interfaces:
  `Iterator<O>`

Direct Known Subclasses:
  `AbstractIteratorDecorator`

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