end

#conjunction? ⇒ Boolean

Return true of this precondition represents a conjunction with nested preconditions or false of this precondition is a reference to a data criteria if it is an observation population criteria, then it is not a conjunction, it is instead doing a calculation

Returns:

  • (Boolean)

end

#conjunction_code ⇒ String

Get the conjunction code, e.g. allTrue, atLeastOneTrue

Returns:

  • (String) —
