Function: parseHd()

parseHd(rep, enc): HD

Parse an HL7 v2 HD repetition into a structured HD object. Components are returned verbatim (already decoded once by the tokenizer: never re-unescaped). Absent / empty components are OMITTED from the result (exactOptionalPropertyTypes semantics).

Parameters

rep

RawRepetition

enc

EncodingCharacters

Returns

HD

Example

import { parseHd, DEFAULT_ENCODING_CHARACTERS } from "@cosyte/hl7";
const rep = { components: [
  { subcomponents: ["EPIC"] },
  { subcomponents: ["1.2.840.114350"] },
  { subcomponents: ["ISO"] },
] };
const hd = parseHd(rep, DEFAULT_ENCODING_CHARACTERS);
console.log(hd.namespaceId);     // "EPIC"
console.log(hd.universalIdType); // "ISO"
