## [Java] Class ContextualClassCodeVisitor

- org.codehaus.groovy.macro.matcher.ContextualClassCodeVisitor

-     public abstract class ContextualClassCodeVisitor
      extends ClassCodeVisitorSupport

  A class code visitor which is capable of remembering the context of the current visit. This makes it easier for subclasses to perform context-dependent transformations, where for example it is necessary to check the parent nodes of an AST node before performing some operations.

  Since:
    2.5.0
