#create_group_data_criteria(preconditions, type, value, parent_id, id, standard_category, qds_data_type) ⇒ Object

grouping data criteria are used to allow a single reference off of a temporal reference or subset operator grouping data criteria can reference either regular data criteria as children, or other grouping data criteria

#duplicate_data_criteria(data_criteria, parent_id) ⇒ Object

duplicates a data criteria. This is important because we may be modifying source data criteria like patient characteristic birthdate to add restrictions the restrictions added may be different for the numerator, denominator, different IPP_1, IPP_2, etc.
