public abstract class AbstractObjectIterator<K> extends Object implements ObjectIterator<K>
An abstract class facilitating the creation of type-specific iterators.To create a type-specific iterator you need both a method returning the next element as primitive type and a method returning the next element as an object. However, if you inherit from this class you need just one (anyone).
This class implements also a trivial version of
skip(int)
that uses type-specific methods; moreover,remove()
will throw anUnsupportedOperationException
.- See Also:
