[Java] Class UnaryExpressionHelper

    java.lang.Object
      org.codehaus.groovy.classgen.asm.UnaryExpressionHelper

    public class UnaryExpressionHelper
    extends java.lang.Object

A 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.
