Interface IContextValidationSupport<EVS_IN,EVS_OUT,SDT,CST,CDCT,IST>

public interface IContextValidationSupport<EVS_IN,EVS_OUT,SDT,CST,CDCT,IST>

This interface is a version-independent representation of the various functions that can be provided by validation and terminology services.

Implementations are not required to implement all of the functions in this interface; in fact it is expected that most won't. Any methods which are not implemented may simply return null and calling code is expected to be able to handle this.

Method Detail

expandValueSet

EVS_OUT expandValueSet(FhirContext theContext,
                       EVS_IN theInclude)

Expands the given portion of a ValueSet

Parameters:

theInclude - The portion to include

Returns:

The expansion

fetchAllConformanceResources

List<IBaseResource> fetchAllConformanceResources(FhirContext theContext)

Load and return all conformance resources associated with this validation support module. This method may return null if it doesn't make sense for a given module.

fetchAllStructureDefinitions

List<SDT> fetchAllStructureDefinitions(FhirContext theContext)

Load and return all possible structure definitions

fetchCodeSystem

CST fetchCodeSystem(FhirContext theContext,
                    String theSystem)

Fetch a code system by ID

Parameters:

theSystem - The code system

Returns:

The valueset (must not be null, but can be an empty ValueSet)

fetchResource

<T extends IBaseResource> T fetchResource(FhirContext theContext,
                                          Class<T> theClass,
                                          String theUri)

Loads a resource needed by the validation (a StructureDefinition, or a ValueSet)

Parameters:

theContext - The HAPI FHIR Context object current in use by the validator

theClass - The type of the resource to load

theUri - The resource URI

Returns:

Returns the resource, or null if no resource with the given URI can be found

fetchStructureDefinition

SDT fetchStructureDefinition(FhirContext theCtx,
                             String theUrl)

isCodeSystemSupported

boolean isCodeSystemSupported(FhirContext theContext,
                              String theSystem)

Returns true if codes in the given code system can be expanded or validated

Parameters:

theSystem - The URI for the code system, e.g. "http://loinc.org"

Returns:

Returns true if codes in the given code system can be validated

validateCode

IContextValidationSupport.CodeValidationResult<CDCT,IST> validateCode(FhirContext theContext,
                                                                      String theCodeSystem,
                                                                      String theCode,
                                                                      String theDisplay)

Validates that the given code exists and if possible returns a display name. This method is called to check codes which are found in "example" binding fields (e.g. Observation.code in the default profile.

Parameters:

theCodeSystem - The code system, e.g. "http://loinc.org"

theCode - The code, e.g. "1234-5"

theDisplay - The display name, if it should also be validated

Returns:

Returns a validation result object

lookupCode

IContextValidationSupport.LookupCodeResult lookupCode(FhirContext theContext,
                                                      String theSystem,
                                                      String theCode)

Look up a code using the system and code value

Parameters:

theContext - The FHIR context

theSystem - The CodeSystem URL

theCode - The code
