Method Detail

fetchCodeSystem

public ValueSet fetchCodeSystem(String system)

Description copied from interface: IWorkerContext

Find a value set for the nominated system uri. return null if there isn't one (then the tool might try supportsSystem)

Specified by:

fetchCodeSystem in interface IWorkerContext

Returns:

supportsSystem

public boolean supportsSystem(String system)

Description copied from interface: IWorkerContext

True if the underlying terminology service provider will do expansion and code validation for the terminology. Corresponds to the extension http://hl7.org/fhir/StructureDefinition/conformance-supported-system in the Conformance resource

Specified by:

supportsSystem in interface IWorkerContext

Returns:

expandVS

public ValueSetExpander.ValueSetExpansionOutcome expandVS(ValueSet vs,
                                                          boolean cacheOk)

Description copied from interface: IWorkerContext

ValueSet Expansion - see $expand

Specified by:

expandVS in interface IWorkerContext

Returns:

expandVS

public ValueSet.ValueSetExpansionComponent expandVS(ValueSet.ConceptSetComponent inc)

Description copied from interface: IWorkerContext

Value set expanion inside the internal expansion engine - used for references to supported system (see "supportsSystem") for which there is no value set.

Specified by:

expandVS in interface IWorkerContext

Returns:

validateCode

public IWorkerContext.ValidationResult validateCode(String system,
                                                    String code,
                                                    String display)

Description copied from interface: IWorkerContext

Validation of a code - consult the terminology service to see whether it is known. If known, return a description of it note: always return a result, with either an error or a code description corresponds to 2 terminology service calls: $validate-code and $lookup

Specified by:

validateCode in interface IWorkerContext

Returns:

validateCode

public IWorkerContext.ValidationResult validateCode(Coding code,
                                                    ValueSet vs)

Specified by:

                                                    ValueSet vs)

Description copied from interface: IWorkerContext

Validation of a code - consult the terminology service to see whether it is known. If known, return a description of it Also, check whether it's in the provided value set note: always return a result, with either an error or a code description, or both (e.g. known code, but not in the value set) corresponds to 2 terminology service calls: $validate-code and $lookup

Specified by:

validateCode in interface IWorkerContext

Returns:

validateCode

public IWorkerContext.ValidationResult validateCode(String system,
                                                    String code,

Description copied from interface: IWorkerContext

Validation of a code - consult the terminology service to see whether it is known. If known, return a description of it Also, check whether it's in the provided value set fragment (for supported systems with no value set definition) note: always return a result, with either an error or a code description, or both (e.g. known code, but not in the value set) corresponds to 2 terminology service calls: $validate-code and $lookup

Specified by:

validateCode in interface IWorkerContext

Returns:

findMapsForSource

public List<ConceptMap> findMapsForSource(String url)

Description copied from interface: IWorkerContext

find concept maps for a source

Specified by:

findMapsForSource in interface IWorkerContext

Returns:

fetchTypeDefinition

public StructureDefinition fetchTypeDefinition(String typeName)

Specified by:
