Class AbstractIntIterator

java.lang.Object

it.unimi.dsi.fastutil.ints.AbstractIntIterator

All Implemented Interfaces:

IntIterator, java.util.Iterator<java.lang.Integer>

Direct Known Subclasses:

AbstractIntBidirectionalIterator, IntIterators.UnmodifiableIterator

public abstract class AbstractIntIterator
extends java.lang.Object
implements IntIterator

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 an UnsupportedOperationException.
