public class UnaryExpressionHelper
extends ObjectA helper class used to generate bytecode for unary expressions. AST transformations willing to use a custom unary expression helper may set the WriterControllerFactory node metadata on a class node to provide a custom WriterController which would in turn use a custom expression helper.
