      `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​(String methodName)

  - ### getCategoryName

    String getCategoryName​(ClassNode classNode, String categoryName)

  - ### wrapLoggingMethodCall

    Expression wrapLoggingMethodCall​(Expression logVariable, String methodName, Expression originalExpression)
