Method Detail

readAllCodeSystems

java.util.Map<java.lang.String,java.lang.Integer> readAllCodeSystems()
                                                                    throws FHIRPersistenceDBConnectException,
                                                                           FHIRPersistenceDataAccessException

Reads all rows in the code_systems table and returns the data as a Map

Returns:

A map containing key=system-name, value=system-id

Throws:

FHIRPersistenceDBConnectException

FHIRPersistenceDataAccessException

readOrAddCodeSystem

int readOrAddCodeSystem(java.lang.String codeSystem)
                 throws FHIRPersistenceDBConnectException,
                        FHIRPersistenceDataAccessException

Reads the id associated with the name of the passed Parameter from the code_systems table. If the id for the passed name is not present in the database, an id is generated, persisted, and returned. This is done in a thread-safe way

Parameters:

codeSystem - A valid FHIR search parameter name.

Returns:

the id associated with the name of the passed Parameter.

Throws:

FHIRPersistenceDBConnectException

FHIRPersistenceDataAccessException

readCodeSystemId

java.lang.Integer readCodeSystemId(java.lang.String codeSystem)
                            throws FHIRPersistenceDBConnectException,
                                   FHIRPersistenceDataAccessException

Read the code_system_id for the given code system name

Parameters:

codeSystem -

Returns:

the parameter_name_id for for parameter, or null if it doesn't exist

Throws:

FHIRPersistenceDBConnectException

FHIRPersistenceDataAccessException
