Method Detail

getResourceTypeId

public Integer getResourceTypeId(String resourceType)
                          throws com.ibm.fhir.persistence.exception.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:

com.ibm.fhir.persistence.exception.FHIRPersistenceException

getResourceTypeName

public String getResourceTypeName(Integer resourceTypeId)
                           throws com.ibm.fhir.persistence.exception.FHIRPersistenceException

Description copied from interface: JDBCIdentityCache

Get the resource type name for the resourceTypeId. Reads from a cache or database if required.

Specified by:

getResourceTypeName in interface JDBCIdentityCache

Returns:

Throws:

com.ibm.fhir.persistence.exception.FHIRPersistenceException

getCodeSystemId

public Integer getCodeSystemId(String codeSystemName)
                        throws com.ibm.fhir.persistence.exception.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:

com.ibm.fhir.persistence.exception.FHIRPersistenceException

getParameterNameId

public Integer getParameterNameId(String parameterName)
                           throws com.ibm.fhir.persistence.exception.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:

com.ibm.fhir.persistence.exception.FHIRPersistenceException

getCanonicalId

public Integer getCanonicalId(String canonicalValue)
                       throws com.ibm.fhir.persistence.exception.FHIRPersistenceException

Description copied from interface: JDBCIdentityCache

Get the database id for the given canonical value. Read only. If the value does not exist, -1 is returned.

Specified by:

getCanonicalId in interface JDBCIdentityCache

Returns:

Throws:

com.ibm.fhir.persistence.exception.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

Returns:

The common token value id or null if it doesn't exist

getCommonTokenValueIds

public Set<Long> getCommonTokenValueIds(Collection<CommonTokenValue> tokenValues)

Description copied from interface: JDBCIdentityCache

Get the common_token_value_ids for the given tokenValues. Reads from a cache, or the database if not found in the cache. CommonTokenValues with no corresponding record in the database will be omitted from the result set.

Specified by:

getCommonTokenValueIds in interface JDBCIdentityCache

Returns:

A non-null, possibly-empty set of common token value ids

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:

getResourceTypeNames

public List<String> getResourceTypeNames()
                                  throws com.ibm.fhir.persistence.exception.FHIRPersistenceException

Description copied from interface: JDBCIdentityCache

Get the list of all resource type names.

Specified by:

getResourceTypeNames in interface JDBCIdentityCache

Returns:

Throws:

com.ibm.fhir.persistence.exception.FHIRPersistenceException

getResourceTypeIds

public List<Integer> getResourceTypeIds()
                                 throws com.ibm.fhir.persistence.exception.FHIRPersistenceException

Description copied from interface: JDBCIdentityCache

Get the list of all resource type ids.

Specified by:

getResourceTypeIds in interface JDBCIdentityCache

Returns:

Throws:

com.ibm.fhir.persistence.exception.FHIRPersistenceException
