public class TransformExpressionKey
extends Object
implements Serializable

The key applies to describe the information of the transformation expression.

A transform expression key contains:

• argumentNames: a list for the argument names in expression.
• argumentClasses: a list for the argument classes in expression.
• returnClass: a class for the return class in expression
