/**
* Functional test for enum mapping as described
* <a href=http://dozer.sourceforge.net/documentation/enum.html>here</a>.
*
* In this functional test, Enum is categorized into two types: Based Enum and Overrided Enum.
* Based Enum refers to those enum without any overrided methods, including constructors. A
* typical Based Enum would look as below.
* <code><pre>
* public enum SrcType {
* FOO , BAR;
* }
* </pre></code>
* On the contrary, Overrided Enum refers to those enum with overrided methods, including
* constructors. A typical Overrided Enum would look as below.
* <code><pre>
* public enum SrcTypeWithOverride {
* FOO { public String display() { return "Src.FOO"; } },
* BAR { public String display() { return "Src.BAR"; } };
* public abstract String display();
* }
* </pre></code>
