Annotation Interface ModifyExpressionValue

@Target(METHOD) @Retention(RUNTIME) public @interface ModifyExpressionValue
Allows you to tweak the resultant value of a method call, field get, constant or object instantiation.

Your handler method receives the expression's resultant value (optionally followed by the enclosing method's parameters), and should return the adjusted value: 

 private (static) ExpressionType handler(ExpressionType original)
This chains when used by multiple people, unlike @Redirect and @ModifyConstant.

If you never use the original then you risk other people's changes being silently ignored.

See the wiki article for more info.
