Class PrimitiveIteratorConverters

java.lang.Object

scala.compat.java8.PrimitiveIteratorConverters

public class PrimitiveIteratorConverters
extends java.lang.Object

This class enables conversion from scala.Iterator to the set of java.util.PrimitiveIterator classes.

Scala's Iterator is generic, as is its java.util counterpart. However, java.util.PrimitiveIterator offers three manually-specialized variants of Iterator: OfDouble, OfInt, and OfLong. This class provides .asPrimitive extension methods for Scala and Java iterators to present the generic versions as the specialized version.

Example usage:

 import scala.compat.java8.PrimitiveIteratorConverters._
 val it = Iterator(1.0, 2.0, math.Pi)
 val jpid = it.asPrimitive   // PrimitiveIterator.OfDouble
