public class Compare
extends DynamoServlet

The Compare servlet renders one of its oparms based on the relative values of the obj1 and obj2 input params. It takes as parameters:

obj1

the first object to be compared. the object must be an instance of comparable. think of this object as the left side of the equation or inequation. e.g. obj1 > obj2

obj2

the second object to be compared. the object must be an instance of comparable. think of this object as the right side of the equation or inequation. e.g. obj1 > obj2

It renders the following oparams:

output

In the output param, we set the param value which is the value returned by calling compare(obj1, obj2), converted to a String.

greaterthan

This oparam is rendered if obj1 > obj2.

lessthan

This oparam is rendered if obj1 < obj2.

equal

This oparam is rendered if obj1 == obj2.

noncomparable

This oparam is rendered the objects cannot be compared.

default

This oparam is rendered if no other oparam has been handled, or if either parameter is null.
