Method Details

getLinkUrlOfType

public static String getLinkUrlOfType(FhirContext theContext,
 IBaseBundle theBundle,
 String theLinkRelation)

Returns:

Returns null if the link isn't found or has no value

getBundleEntryUrlsAndResources

public static List<org.apache.commons.lang3.tuple.Pair<String,IBaseResource>> getBundleEntryUrlsAndResources(FhirContext theContext,
 IBaseBundle theBundle)

getBundleType

public static String getBundleType(FhirContext theContext,
 IBaseBundle theBundle)

setBundleType

public static void setBundleType(FhirContext theContext,
 IBaseBundle theBundle,
 String theType)

getTotal

public static Integer getTotal(FhirContext theContext,
 IBaseBundle theBundle)

setTotal

public static void setTotal(FhirContext theContext,
 IBaseBundle theBundle,
 Integer theTotal)

toListOfEntries

public static List<BundleEntryParts> toListOfEntries(FhirContext theContext,
 IBaseBundle theBundle)

Extract all of the resources from a given bundle

sortEntriesIntoProcessingOrder

public static void sortEntriesIntoProcessingOrder(FhirContext theContext,
 IBaseBundle theBundle)
                                           throws IllegalStateException

Function which will do an in-place sort of a bundles' entries, to the correct processing order, which is: 1. Deletes 2. Creates 3. Updates Furthermore, within these operation types, the entries will be sorted based on the order in which they should be processed e.g. if you have 2 CREATEs, one for a Patient, and one for an Observation which has this Patient as its Subject, the patient will come first, then the observation. In cases of there being a cyclic dependency (e.g. Organization/1 is partOf Organization/2 and Organization/2 is partOf Organization/1) this function will throw an IllegalStateException.

Parameters:

theContext - The FhirContext.

theBundle - The IBaseBundle which contains the entries you would like sorted into processing order.

Throws:

IllegalStateException

processEntries

public static void processEntries(FhirContext theContext,
 IBaseBundle theBundle,
 Consumer<ModifiableBundleEntry> theProcessor)

Given a bundle, and a consumer, apply the consumer to each entry in the bundle.

Parameters:

theContext - The FHIR Context

theBundle - The bundle to have its entries processed.

theProcessor - a Consumer which will operate on all the entries of a bundle.

toListOfResources

public static List<IBaseResource> toListOfResources(FhirContext theContext,
 IBaseBundle theBundle)

Extract all of the resources from a given bundle

toListOfResourcesOfType

public static <T extends IBaseResource> List<T> toListOfResourcesOfType(FhirContext theContext,
 IBaseBundle theBundle,
 Class<T> theTypeToInclude)

Extract all of the resources of a given type from a given bundle

isDstu3TransactionPatch

public static boolean isDstu3TransactionPatch(FhirContext theContext,
 IBaseResource thePayloadResource)

DSTU3 did not allow the PATCH verb for transaction bundles- so instead we infer that a bundle is a patch if the payload is a binary resource containing a patch. This method tests whether a resource (which should have come from Bundle.entry.resource is a Binary resource with a patch payload type.
