Method Detail
-
getResourceTypeId
public java.lang.Integer getResourceTypeId(java.lang.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 interfaceJDBCIdentityCache
- Returns:
- Throws:
FHIRPersistenceException
-
getResourceTypeName
public java.lang.String getResourceTypeName(java.lang.Integer resourceTypeId) throws 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 interfaceJDBCIdentityCache
- Returns:
- Throws:
FHIRPersistenceException
-
getCodeSystemId
public java.lang.Integer getCodeSystemId(java.lang.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 interfaceJDBCIdentityCache
- Returns:
- Throws:
FHIRPersistenceException
-
getParameterNameId
public java.lang.Integer getParameterNameId(java.lang.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 interfaceJDBCIdentityCache
- Returns:
- Throws:
FHIRPersistenceException
-
getCanonicalId
public java.lang.Long getCanonicalId(java.lang.String canonicalValue) throws 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 interfaceJDBCIdentityCache
- Returns:
- Throws:
FHIRPersistenceException
-
getCommonTokenValueId
public java.lang.Long getCommonTokenValueId(java.lang.String codeSystem, java.lang.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 interfaceJDBCIdentityCache
- Returns:
- The common token value id or null if it doesn't exist
-
getCommonTokenValueIds
public java.util.Set<java.lang.Long> getCommonTokenValueIds(java.util.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 interfaceJDBCIdentityCache
- Returns:
- A non-null, possibly-empty set of common token value ids
-
getCommonTokenValueIdList
public java.util.List<java.lang.Long> getCommonTokenValueIdList(java.lang.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 interfaceJDBCIdentityCache
- Returns:
-
getResourceTypeNames
public java.util.List<java.lang.String> getResourceTypeNames() throws FHIRPersistenceException
Description copied from interface:JDBCIdentityCache
Get the list of all resource type names.- Specified by:
getResourceTypeNames
in interfaceJDBCIdentityCache
- Returns:
- Throws:
FHIRPersistenceException
-
getResourceTypeIds
public java.util.List<java.lang.Integer> getResourceTypeIds() throws FHIRPersistenceException
Description copied from interface:JDBCIdentityCache
Get the list of all resource type ids.- Specified by:
getResourceTypeIds
in interfaceJDBCIdentityCache
- Returns:
- Throws:
FHIRPersistenceException
-
getLogicalResourceId
public java.lang.Long getLogicalResourceId(java.lang.String resourceType, java.lang.String logicalId) throws FHIRPersistenceException
Description copied from interface:JDBCIdentityCache
Get the database id for the given (resourceType, logicalId) tuple. This represents records in logical_resource_ident which may be created before the actual resource is created.- Specified by:
getLogicalResourceId
in interfaceJDBCIdentityCache
- Returns:
- Throws:
FHIRPersistenceException
-
getLogicalResourceIds
public java.util.Set<java.lang.Long> getLogicalResourceIds(java.util.Collection<ResourceReferenceValue> referenceValues) throws FHIRPersistenceException
Description copied from interface:JDBCIdentityCache
Get the logical_resource_ids for the given referenceValues. Reads from a cache, or the database if not found in the cache. Values with no corresponding record in the database will be omitted from the result set.- Specified by:
getLogicalResourceIds
in interfaceJDBCIdentityCache
- Returns:
- a non-null, possibly empty set of logical_resource_ids.
- Throws:
FHIRPersistenceException
-
getLogicalResourceIdList
public java.util.List<java.lang.Long> getLogicalResourceIdList(java.lang.String logicalId) throws FHIRPersistenceException
Description copied from interface:JDBCIdentityCache
Get a list of logical_resource_id values matching the given logicalId without knowing the resource type. This means we could get back multiple ids, one per resource type, such as:- Claim/foo
- Observation/foo
- Patient/foo
- Specified by:
getLogicalResourceIdList
in interfaceJDBCIdentityCache
- Returns:
- Throws:
FHIRPersistenceException
