Method Details

expandSearchAndStoreInRequestDetails

public MdmSearchExpansionResults expandSearchAndStoreInRequestDetails(String theResourceName,
 @Nullable
 ca.uhn.fhir.rest.api.server.RequestDetails theRequestDetails,
 @Nonnull
 ca.uhn.fhir.jpa.searchparam.SearchParameterMap theSearchParameterMap,
 MdmSearchExpansionSvc.IParamTester theParamTester)

This method looks through all the reference parameters within a SearchParameterMap and performs MDM expansion. This means looking for any subject/patient parameters, and expanding them to include any linked and golden resource patients. So, for example, a search for Encounter?subject=Patient/1 might be modified to be a search for Encounter?subject=Patient/1,Patient/999 if 999 is linked to 1 by MDM.

This is an internal MDM service and its API is subject to change. Use with caution!

Parameters:

theRequestDetails - The incoming request details

theSearchParameterMap - The parameter map to modify

theParamTester - Determines which parameters should be expanded

Returns:

Returns the results of the expansion, which are also stored in the RequestDetails userdata map, so this service will only be invoked a maximum of once per request.

Since:
