hapi.context.getR4bFhirContext

Signature: hapi.context.getR4bFhirContext(useNarrative*, useUSCoreProfile*)

Returns: FhirContext fhirContext - the cached FhirContext for R4b

Returns the R4b FhirContext for parsing and serializing HAPI resources.

This threadsafe instance is cached, and therefore optimized for use within QIE.

Note

Parsing Usage: var parser = hapi.context.getR4bFhirContext().newJsonParser(); var hapiPatient = parser.parseResource(patientJsonString);

Note

Serializing Usage: var parser = hapi.context.getR4bFhirContext().newJsonParser(); var patientJsonString = parser.encodeResourceToString(hapiPatient);

Parameters

Type	Name	Description	Default
Boolean	useNarrative*	(optional) if true, includes a narrative text based on the resource	false
Boolean	useUSCoreProfile*	(optional) if true, includes USCoreProfile extensions	false

Example

// Get the HAPI fhir context you want (2/3/4b) etc.
var fhirContext = hapi.context.getR4bFhirContext();

// now you can do things with fhirContext
var patientJson = '' +
   '{' +
   '    "resourceType": "Patient",' +
   '    "id": "example",' +
   '    "name": [' +
   '        {' +
   '            "family": "Doe",' +
   '            "given": ["John","Jaques"]' +
   '        }' +
   '    ],' +
   '    "gender": "male",' +
   '    "birthDate": "1980-01-01"' +
   '}';

// Use the context to create a parser
var jsonParser = fhirContext.newJsonParser();

// Parse the JSON string into a Patient object
var patient = jsonParser.parseResource(org.hl7.fhir.r4b.model.Patient, patientJson);

// Extract the patient's name
var humanName = patient.name.get(0); // Get the first name in the list
var fullName = humanName.getGiven() + ' ' + humanName.getFamily();
