All Implemented Interfaces:

Serializable

Direct Known Subclasses:

Stu3FhirConversionSupport

public abstract class FhirConversionSupport
extends Object
implements Serializable

Helper functions to allow code to convert FHIR resources independently of the FHIR version. Typically an implementation specific to a FHIR version is provided at runtime.

Method Detail

fhirType

public abstract String fhirType(org.hl7.fhir.instance.model.api.IBase base)

Returns the type of a given FHIR object, such as "Condition" or "Observation".

Parameters:

base - a FHIR object

Returns:

the FHIR type

compositeValues

public abstract Map<String,List> compositeValues(org.hl7.fhir.instance.model.api.IBase composite)

Returns a map of the fields in a composite type to the corresponding values. Since FHIR fields may have multiple values a list is returned, and single-valued items will have a singleton list.

Parameters:

composite - a FHIR composite type

Returns:

a map of field names to the values.

extractEntryFromBundle

public abstract List<org.hl7.fhir.instance.model.api.IBaseResource> extractEntryFromBundle(org.hl7.fhir.instance.model.api.IBaseBundle bundle,
                                                                                           String resourceType)

Extracts resources of the given type from a FHIR bundle.

Parameters:

bundle - the bundle

resourceType - the resource type name, such as "Condition" or "Observation"

Returns:

the resources of the specified type.

supportFor

public static FhirConversionSupport supportFor(ca.uhn.fhir.context.FhirVersionEnum fhirVersion)

Returns the FHIR context for the given version. This is effectively a cache so consuming code does not need to recreate the context repeatedly.

Parameters:

fhirVersion - the version of FHIR to use

Returns:

the FhirContext

forStu3

public static FhirConversionSupport forStu3()

Convenience function to load support for FHIR STU3.

Returns:

the conversion support instance.
