getOrCreateResourceIdentifierSystem

public long getOrCreateResourceIdentifierSystem(ca.uhn.fhir.rest.api.server.RequestDetails theRequestDetails,
 RequestPartitionId theRequestPartitionId,
 String theSystem)

Description copied from interface: IResourceIdentifierCacheSvc

Retrieves (and creates if necessary) the PID associated with the given identifier system URL.

Thread-safety: This method is designed to be thread-safe, including in cases where multiple threads are attempting to create a new FHIR ID for the same identifier system. It will internally retry automatically if multiple threads attempt to create a new identifier system and will not fail in this case.

Transactionality: This method will open a new transaction if one is not already open.

Specified by:

getOrCreateResourceIdentifierSystem in interface IResourceIdentifierCacheSvc

Parameters:

theRequestDetails - The request details associated with the current request

theRequestPartitionId - The partition ID associated with the current request

theSystem - The Identifier.system value

Returns:

Returns a PID associated with the given identifier system URL.

getFhirIdAssociatedWithUniquePatientIdentifier

@Nonnull
public String getFhirIdAssociatedWithUniquePatientIdentifier(ca.uhn.fhir.rest.api.server.RequestDetails theRequestDetails,
 RequestPartitionId theRequestPartitionId,
 String theSystem,
 String theValue,
 Supplier<String> theNewIdSupplier)

Description copied from interface: IResourceIdentifierCacheSvc

Retrieves the FHIR ID associated with the given Patient identifier, creating a new record using the given Supplier if no existing record is found. This method enforces uniqueness on the identifier using a database constraint and will therefore only allow one FHIR ID to be associated with one Identifier. No uniqueness is enforced on the FHIR ID.

Thread safety: This method will fail with a constraint error if multiple threads attempt to assign a FHIR ID for the same system+value combination concurrently.

Transactionality: This method will open a new transaction if one is not already open.

Specified by:

getFhirIdAssociatedWithUniquePatientIdentifier in interface IResourceIdentifierCacheSvc

Parameters:

theSystem - The Identifier.system value

theValue - The Identifier.value value

theNewIdSupplier - If no existing FHIR ID is found, a new entry will be created using this ID supplier

Returns:

The FHIR ID associated with this identifier
