      protected boolean projection
      Instruct the JSON query analyzer if it is a projection

    • position

      protected int position
      The breadcrumb.size() provide the level of nesting. The position which element number at the same level. E.g. the index of a ConsistsOf when the caller is a Resource. It is used in conjunction with breadcrumb.size() to attach a number to the alias. This allows to generate a predictive not clashing alias instead of using random string/number. This is useful for testing purposes.

    • alias

      protected String alias
      Contains the alias if needed by the class

      protected List<String> fieldsToEmit
      This field is used by entry point only. Any class at any level can retrieve the entry point using breadcrumb.get(0);

    • size

      protected int size
      it indicates the number of properties in this.jsonNode This number is manipulated while analyzing the jsonNode to properly create the query.
