    - #### addLoggerFieldToClass

          FieldNode addLoggerFieldToClass(ClassNode classNode,
                                          java.lang.String fieldName,
                                          java.lang.String categoryName)

      In this method, you are given a ClassNode, a field name and a category name, and you must add a new Field onto the class. Return the result of the ClassNode.addField operations.
      Parameters:
        `classNode` - the class that was originally annotated with the Log transformation.
        `fieldName` - the name of the logger field
        `categoryName` - the name of the logging category
      Returns:
        the FieldNode instance that was created and added to the class

    - #### isLoggingMethod

          boolean isLoggingMethod(java.lang.String methodName)

    - #### getCategoryName

          java.lang.String getCategoryName(ClassNode classNode,
                                           java.lang.String categoryName)

    - #### wrapLoggingMethodCall

          Expression wrapLoggingMethodCall(Expression logVariable,
                                           java.lang.String methodName,
                                           Expression originalExpression)
