      • getRelevantAttributes

        AttributeSet getRelevantAttributes()
        Get the set of relevant attribute types.
      • getIndirectAttributes

        AttributeSet getIndirectAttributes()
        Get the set of indirect attribute types. I.e. attributes of objects, which are not part of an object conditions (e.g. for chained extractors)
