Stream: hapi
Topic: Hapi, FHIR R4, Navigating thru MessageHeader object
Zak Guler (Jul 27 2020 at 15:50):
I am receiving a FHIR 'MessageHeader' Document and converting it to Bundle object. I can get the values for some parameters values but not the ones nested deeper inside the object.
for instance:
-I can get the code value for "underlying_cause_of_death": "C509"
as in:
List<String> strListUnderlying = parameters.getParameters("underlying_cause_of_death")
.stream()
.filter(e -> e instanceof Coding)
.map(c -> ((Coding) c).getCode())
.collect(Collectors.toList());
strListUnderlying.forEach(s -> System.out.println("z..underlying_cause_of_death: " + s));
output: "C509"
But, I can't find a way to get the code(s) for "record_cause_of_death": "C509" and "I500".
Can anyone help please show me how to navigate thru this object? example of the file is below.
thank you
Zak
EX: to build the Bundle object:
bundle = (Bundle) ctx.newJsonParser().parseResource(Bundle.class, reqBody);

problem resolved.
List<ParametersParameterComponent> param = parameters.getParameter();
List<ParametersParameterComponent> paramParts4 = param.get(4).getPart();
logger.info("z..paramParts4.size(): " + paramParts4.size());
logger.info("z..paramParts4.get(0).getName(): " + paramParts4.get(0).getName());
logger.info("z..paramParts4.get(0).getValue(): " + paramParts4.get(0).getValue());
logger.info("z..paramParts4.get(1).getName(): " + paramParts4.get(1).getName());
logger.info("z..paramParts4.get(1).getValue(): " + paramParts4.get(1).getValue().getChildByName("code").getValues().toString());
