# Class UnaryExpressionHelper

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

Direct Known Subclasses:
  `StaticTypesUnaryExpressionHelper`

public class UnaryExpressionHelper extends 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.
