Function: get834Enrollments()

get834Enrollments(delimiters, tx): AsyncIterable<X12Enrollment>

Stream the 834 member-level detail loops - one X12Enrollment per INS segment. For a non-834 transaction the iterable yields nothing. Async-generator typed so the contract leaves room for a future file→iterator streaming source; the v1 implementation iterates the already-parsed tx.segments synchronously under the hood.

Parameters

delimiters

Delimiters

tx

X12TransactionSet

Returns

AsyncIterable<X12Enrollment>

Example

import { parseX12, get834Enrollments } from "@cosyte/x12";
const ix = parseX12(raw);
const tx = ix.groups[0]?.transactions.find((t) => t.st.elements[1] === "834");
if (tx !== undefined) {
  for await (const member of get834Enrollments(ix.delimiters, tx)) {
    member.maintenanceTypeCode;      // "021"
    member.member?.idCode;           // verbatim member id
  }
}
