Class CompartmentHelper

  • public class CompartmentHelper
extends java.lang.Object
    A helper class with methods for working with HL7 FHIR compartments.
    The compartments are defined by the CompartmentDefinition resources in FHIRRegistry.
    The R4 CompartmentDefintions and boundaries are defined at https://hl7.org/fhir/R4/compartmentdefinition.html

    Default CompartmentDefintion:
    • Patient - https://hl7.org/fhir/R4/compartmentdefinition-patient.json
    • Encounter - https://hl7.org/fhir/R4/compartmentdefinition-encounter.json
    • RelatedPerson - https://hl7.org/fhir/R4/compartmentdefinition-relatedperson.json
    • Practitioner - https://hl7.org/fhir/R4/compartmentdefinition-practitioner.json
    • Device - https://hl7.org/fhir/R4/compartmentdefinition-device.json
