All Implemented Interfaces:

ResultAdapter<Object>, Comparable<ResultAdapter>

public class NumberIterableResultAdapter
extends AbstractIterableResultAdapter<Object>

This class will adapt results from an iterable object to a number. The future task returned will have already executed with the results available.

It will accept adaptations wherein the original value is some sort of iterable and the required return type is an instance of Number. Additionally, it will check to see if the iterable yields only one item and also that the item is a number.

Here is a list of supported number types:

• Long
• Short
• Integer
• Byte
• Double
• Float

This adapter will execute at priority -425.
