Method Detail

getResourceTypeId

Integer getResourceTypeId(String resourceType)
                   throws FHIRPersistenceException

Get the database id for the named resourceType. Reads from a cache or database if required.

Parameters:

resourceType -

Returns:

Throws:

FHIRPersistenceException

getCodeSystemId

Integer getCodeSystemId(String codeSystem)
                 throws FHIRPersistenceException

Get the database id for the named code-system. Creates new records if necessary

Parameters:

codeSystem -

Returns:

Throws:

FHIRPersistenceException

getParameterNameId

Integer getParameterNameId(String parameterName)
                    throws FHIRPersistenceException

Get the database id for the given parameter name. Creates new records if necessary.

Parameters:

parameterName -

Returns:

Throws:

FHIRPersistenceException

getCommonTokenValueId

Long getCommonTokenValueId(String codeSystem,
                           String tokenValue)

Get the common_token_value_id for the given tokenValue and codeSystem. Reads from a cache, or the database if not found in the cache.

Parameters:

codeSystem -

tokenValue -

getCommonTokenValueIdList

List<Long> getCommonTokenValueIdList(String tokenValue)

Get a list of matching common_token_value_id values. Implementations may decide to cache, but only if the cache can be invalidated when the list changes due to ingestion. The simplest approach is to always read from the database. The performance benefit to the FHIR search query this is being used for is orders of magnitude greater than the cost of this query (think 80+ seconds to 250 milliseconds improvement in search query time).

Parameters:

tokenValue -

Returns:
