Class CompartmentUtil

java.lang.Object

com.ibm.fhir.search.compartment.CompartmentUtil

public class CompartmentUtil
extends Object

This class supplements SearchUtil with compartment-specific utilities.
The compartments are defined using FHIR R4 CompartmentDefinitions.
The R4 CompartmentDefintions and boundaries are defined at https://hl7.org/fhir/R4/compartmentdefinition.html

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

Call init() to initialize static members and avoid a slight performance hit on first use.

Method Detail

init

public static void init()

Loads the class in the classloader to initialize static members. Call this before using the class in order to avoid a slight performance hit on first use.

buildMaps

public static final void buildMaps(Map<String,CompartmentCache> compMap,
                                   Map<String,ResourceCompartmentCache> resourceCompMap)

Builds an in-memory model of the Compartment map defined in compartments.json, for supporting compartment based FHIR searches.

Parameters:

compMap - map of compartment name to CompartmentCache

resourceCompMap - map of resource type name to ResourceCompartmentCache

getCompartmentResourceTypes

public static List<String> getCompartmentResourceTypes(String compartment)
                                                throws FHIRSearchException

gets the compartment

Parameters:

compartment -

Returns:

Throws:

FHIRSearchException

getCompartmentResourceTypeInclusionCriteria

public static List<String> getCompartmentResourceTypeInclusionCriteria(String compartment,
                                                                       String resourceType)
                                                                throws FHIRSearchException

gets the compartment and resource type inclusion criteria.

Parameters:

compartment -

resourceType -

Returns:

Throws:

FHIRSearchException - if the passed resourceType does not exist within the passed compartment

checkValidCompartment

checks that the compartment is valid, and throws and exception if, not

Parameters:

compartment -

Throws:

FHIRSearchException

checkValidCompartmentAndResource

public static void checkValidCompartmentAndResource(String compartment,
                                                    String resourceType)
                                             throws FHIRSearchException

checks that the compartment and resource are valid, and throws and exception if, not
