Class AbstractObjectIterator<K>

java.lang.Object
  it.unimi.dsi.fastutil.objects.AbstractObjectIterator<K>

All Implemented Interfaces:

ObjectIterator<K>, Iterator<K>

Direct Known Subclasses:

AbstractObjectBidirectionalIterator, ObjectIterators.UnmodifiableIterator

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 an UnsupportedOperationException.

Method Summary

void	remove() This method just throws an UnsupportedOperationException.
int	skip(int n) This method just iterates the type-specific version of Iterator.next() for at most n times, stopping if Iterator.hasNext() becomes false.

Specified by:

skip in interface ObjectIterator<K>

Parameters:

n - the number of elements to skip.
