All Implemented Interfaces:

ResultAdapter<Iterator>, Comparable<ResultAdapter>

public class IteratorIterableResultAdapter
extends AbstractIterableResultAdapter<Iterator>

This class will adapt results from an iterable object to an iterator.

It will accept adaptations wherein the original value is some sort of iterable and the required return type is an instance of Iterator. Remember that it does not check for individual object type compatibility.

This adapter will execute at priority -350.
