core.hl7segment.getfield | Medplum
Hl7Segment.getField() method
Returns an HL7 field by index.
Note that the index is 1-based, not 0-based.
For example, to get the first field, use getField(1).
This aligns with HL7 field names such as PID.1, PID.2, etc.
Field zero is the segment name.
Fields are lazily parsed; the requested field is parsed and cached on demand.
Signature:
getField(index: number): Hl7Field;
Parameters
| Parameter | Type | Description |
|---|---|---|
| index | number | The HL7 field index. |
Returns:
Hl7Field
The HL7 field.
