com.ibm.fhir.persistence.jdbc.dao.impl.JDBCIdentityCacheImpl

All Implemented Interfaces:

JDBCIdentityCache

public class JDBCIdentityCacheImpl
extends Object
implements JDBCIdentityCache

Pulls together the DAOs and tenant-specific cache to provide a single place where we can look up the identity of various records we need

Method Detail

getResourceTypeId

public Integer getResourceTypeId(String resourceType)
                          throws FHIRPersistenceException

Description copied from interface: JDBCIdentityCache

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

Specified by:

getResourceTypeId in interface JDBCIdentityCache

Returns:

Throws:

FHIRPersistenceException

getCodeSystemId

public Integer getCodeSystemId(String codeSystemName)
                        throws FHIRPersistenceException

Description copied from interface: JDBCIdentityCache

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

Specified by:

getCodeSystemId in interface JDBCIdentityCache

Returns:

Throws:

FHIRPersistenceException

getParameterNameId

public Integer getParameterNameId(String parameterName)
                           throws FHIRPersistenceException

Description copied from interface: JDBCIdentityCache

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

Specified by:

getParameterNameId in interface JDBCIdentityCache

Returns:

Throws:

FHIRPersistenceException

getCommonTokenValueId

public Long getCommonTokenValueId(String codeSystem,
                                  String tokenValue)

Description copied from interface: JDBCIdentityCache

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.

Specified by:

getCommonTokenValueId in interface JDBCIdentityCache

getCommonTokenValueIdList

public List<Long> getCommonTokenValueIdList(String tokenValue)

Description copied from interface: JDBCIdentityCache

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).

Specified by:

getCommonTokenValueIdList in interface JDBCIdentityCache

Returns:
