com.ioshq.comparator.BeanPropertyComparator
rns -1 c.compare(new PersonBean("Alex"),new PersonBean("Bob")); // returns 0 c.compare(new PersonBean("Alex"),new PersonBean("Alex)); // returns 1 c.compare(new PersonBean("Bob"),new PersonBean("Bob")); Note the property is the name of a JavaBeans property, and according to the JavaBeans specification must start with a lower case letter. So, the property name is translated to the method getName() using the standard {@link java.beans.Introspector}process.
Note this uses the {@link java.beans.BeanInfo} class to obtain theaccessor method, so that provided a {@link java.beans.BeanInfo} is given, it will work regardless of the nameof the read method. @author Alex Blewitt <Alex.Blewitt@ioshq.com> @version 1.0
