java.lang.Object
  com.wordpress.tipsforjava.util.BeanComparator
All Implemented Interfaces:
Comparator
public class BeanComparator
extends Object

A comparator to sort on the specified field of a given class. Reflection is used to retrieve the data to be sorted, therefore you must provide the Class and the method name within the class that will be used to retrieve the data. Several sort properties can be set: a) ascending (default true) b) ignore case (default true) c) nulls last (default true)
