Class Iterators.PrimitiveInt

java.lang.Object
  com.aliasi.util.Iterators.PrimitiveInt

All Implemented Interfaces:

Iterator<Integer>

Enclosing class:

Iterators

public abstract static class Iterators.PrimitiveInt
extends Object
implements Iterator<Integer>

A Iterators.PrimitiveInt is an integer iterator that also allows objects to be accessed as primitive int values.

The method next() returns an Integer, whereas nextPrimitive() returns a primitive int value. Using either one will advanced the iterator to the next element.

Implementation Note: Using the standard iterator implementation as Integer requires boxing of the primitive values as objects. Therefore, use the method nextPrimitive() wherever possible.
