getVersionMap

@Nonnull
public ResourceVersionMap getVersionMap(RequestPartitionId theRequestPartitionId,
 String theResourceName,
 SearchParameterMap theSearchParamMap)

Specified by:

getVersionMap in interface IResourceVersionSvc

getLatestVersionIdsForResourceIds

public ResourcePersistentIdMap getLatestVersionIdsForResourceIds(RequestPartitionId theRequestPartitionId,
 List<org.hl7.fhir.instance.model.api.IIdType> theIds)

Retrieves the latest versions for any resourceid that are found. If they are not found, they will not be contained in the returned map. The key should be the same value that was passed in to allow consumer to look up the value using the id they already have. This method should not throw, so it can safely be consumed in transactions.

Specified by:

getLatestVersionIdsForResourceIds in interface IResourceVersionSvc

Parameters:

theRequestPartitionId - - request partition id

theIds - - list of IIdTypes for resources of interest.
