Method Detail

readAllSearchParameterNames

Map<String,Integer> readAllSearchParameterNames()
                                               throws FHIRPersistenceDBConnectException,
                                                      FHIRPersistenceDataAccessException

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

Returns:

Map - A map containing key=parameter-name, value=parameter-name-id

Throws:

FHIRPersistenceDBConnectException

FHIRPersistenceDataAccessException

readAllCodeSystems

Map<String,Integer> readAllCodeSystems()
                                      throws FHIRPersistenceDBConnectException,
                                             FHIRPersistenceDataAccessException

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

Returns:

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

Throws:

FHIRPersistenceDBConnectException

FHIRPersistenceDataAccessException

readOrAddParameterNameId

int readOrAddParameterNameId(String parameterName)
                      throws FHIRPersistenceDBConnectException,
                             FHIRPersistenceDataAccessException

Reads the id associated with the name of the passed Parameter from the Parameter_Names table. If the id for the passed name is not present in the database, an id is generated, persisted, and returned.

Parameters:

String - A valid FHIR search parameter name.

Returns:

Integer - the id associated with the name of the passed Parameter.

Throws:

FHIRPersistenceDBConnectException

FHIRPersistenceDataAccessException

readParameterNameId

Integer readParameterNameId(String parameterName)
                     throws FHIRPersistenceDBConnectException,
                            FHIRPersistenceDataAccessException

Read the id for the given parameter name, but do not create a new record if it doesn't exist.

Parameters:

parameterName -

Returns:

the id for the parameter name, or null not found

Throws:

FHIRPersistenceDBConnectException

FHIRPersistenceDataAccessException

readOrAddCodeSystemId

int readOrAddCodeSystemId(String systemName)
                   throws FHIRPersistenceDBConnectException,
                          FHIRPersistenceDataAccessException

Reads the id associated with the name of the passed code system name from the Code_Systems table. If the id for the passed system name is not present in the database, an id is generated, persisted, and returned.

Parameters:

systemName - - The name of a FHIR code system.

Returns:

Integer - The id associated with the passed code system name.

Throws:

FHIRPersistenceDBConnectException

FHIRPersistenceDataAccessException

readCodeSystemId

Integer readCodeSystemId(String systemName)
                  throws FHIRPersistenceDBConnectException,
                         FHIRPersistenceDataAccessException

Read the id for the given code system name, but do not create a new record if it doesn't exist.

Parameters:

systemName -

Returns:

Integer - The id associated with the passed code system name, or null if it doesn't exist

Throws:

FHIRPersistenceDBConnectException

FHIRPersistenceDataAccessException

acquireParameterNameId

int acquireParameterNameId(String parameterName)
                    throws FHIRPersistenceException

Acquire and return the id associated with the passed parameter name.

Parameters:

parameterName - The name of a valid FHIR search parameter.

Returns:

Integer A parameter id.

Throws:

FHIRPersistenceException

acquireCodeSystemId

int acquireCodeSystemId(String codeSystemName)
                 throws FHIRPersistenceException

Acquire and return the id associated with the passed code-system name.

Parameters:

codeSystemName - The name of a valid code-system.

Returns:

Integer A code-system id.

Throws:

FHIRPersistenceException

addParameterNamesCacheCandidate

void addParameterNamesCacheCandidate(String parameterName,
                                     Integer parameterId)
                              throws FHIRPersistenceException

Adds a parameter name / parameter id pair to a candidate collection for population into the ParameterNamesCache. This pair must be present as a row in the FHIR DB PARAMETER_NAMES table.

Parameters:

parameterName - A valid search or sort parameter name.

parameterId - The id corresponding to the parameter name.

Throws:

FHIRPersistenceException
