Description copied from interface: FHIRPersistence

Stores a new FHIR Resource in the datastore. Id assignment handled by the implementation. This method has been deprecated. Instead, generate the logical id first and use the createWithMeta(context, resource) call instead.

Specified by:

create in interface FHIRPersistence

Parameters:

context - the FHIRPersistenceContext instance associated with the current request

resource - the FHIR Resource instance to be created in the datastore

Returns:

a SingleResourceResult with a copy of resource with Meta fields updated by the persistence layer and/or an OperationOutcome with hints, warnings, or errors related to the interaction

Throws:

FHIRPersistenceException

createWithMeta

Specified by:

createWithMeta in interface FHIRPersistence

Parameters:

context - the FHIRPersistenceContext instance associated with the current request

updatedResource - the FHIR Resource instance to be created in the datastore

generateResourceId

public String generateResourceId()

Description copied from interface: FHIRPersistence

Generates a resource ID.

Specified by:

                                      throws FHIRPersistenceException

Called just prior to commit so that we can persist all the token value records that have been accumulated during the transaction. This collection therefore contains multiple resource types, which have to be processed separately.

Parameters:

records -

profileRecs -

tagRecs -

securityRecs -

Throws:

FHIRPersistenceException

fetchResourcePayloads

Description copied from interface: FHIRPersistence

Special function for high speed export of resource payloads. The process function must process the InputStream before returning. Result processing will be stopped if the process function returns Boolean FALSE.

Specified by:

fetchResourcePayloads in interface FHIRPersistence

Parameters:

resourceType - the resource type which is the target of the search

fromLastModified - start reading from this timestamp

toLastModified - do not read beyond this timestamp

processor - function to process each payload record

Returns:

the last ResourcePayload processed, or null if no data was found

Throws:

FHIRPersistenceException

retrieveIndex

public List<Long> retrieveIndex(int count,
                                Instant notModifiedAfter,

                         throws FHIRPersistenceException

Description copied from interface: FHIRPersistence

Retrieves a list of index IDs available for reindexing.

Specified by:

retrieveIndex in interface FHIRPersistence

Parameters:

count - the maximum nuber of index IDs to retrieve

notModifiedAfter - only retrieve index IDs for resources not last updated after the specified timestamp

afterIndexId - retrieve index IDs starting after this specified index ID, or null to start with first index ID

resourceTypeName - the resource type of index IDs to return, or null

Returns:

list of index IDs available for reindexing

Throws:

FHIRPersistenceException

isUpdateCreateEnabled

public boolean isUpdateCreateEnabled()

Description copied from interface: FHIRPersistence

Returns true iff the persistence layer implementation supports update/create and it has been configured in the persistence config.

Specified by:

Returns:

storePayload

public Future<PayloadKey> storePayload(Resource resource,
                                       String logicalId,
                                       int newVersionNumber)
                                throws FHIRPersistenceException

Description copied from interface: FHIRPersistence

Offload payload storage to another provider. If result is not null, the returned Future can be used to obtain the status of the operation. If the result is null, then the implementation does not support offloading and the payload must be stored in the traditional manner (e.g. in the RDBMS). A Future is used because the offloading storage operation may be asynchronous.

Specified by:

storePayload in interface FHIRPersistence

Returns:

Throws:

FHIRPersistenceException
