Description copied from interface: FHIRPersistenceJDBCCache

Getter for the common values cache

Specified by:

getCommonValuesCache in interface FHIRPersistenceJDBCCache

Returns:

the resourceReferenceCache

getResourceTypeCache

public INameIdCache<java.lang.Integer> getResourceTypeCache()

Description copied from interface: FHIRPersistenceJDBCCache

Getter for the cache of resource types used to look up resource type id

Specified by:

getResourceTypeCache in interface FHIRPersistenceJDBCCache

Returns:

the resourceTypeCache

getResourceTypeNameCache

public IIdNameCache<java.lang.Integer> getResourceTypeNameCache()

Description copied from interface: FHIRPersistenceJDBCCache

Getter for the cache of resource type ids used to look up resource type name

Specified by:

getResourceTypeNameCache in interface FHIRPersistenceJDBCCache

Returns:

the resourceTypeNameCache

getParameterNameCache

public INameIdCache<java.lang.Integer> getParameterNameCache()

Description copied from interface: FHIRPersistenceJDBCCache

Getter for the cache of parameter names

Specified by:

getParameterNameCache in interface FHIRPersistenceJDBCCache

Returns:

the parameterNameCache

getLogicalResourceIdentCache

public ILogicalResourceIdentCache getLogicalResourceIdentCache()

Description copied from interface: FHIRPersistenceJDBCCache

Getter for the cache handling lookups for logical_resource_id values

Specified by:

getLogicalResourceIdentCache in interface FHIRPersistenceJDBCCache

Tell any caches that the transaction on the current thread has just committed

Specified by:

transactionCommitted in interface FHIRPersistenceJDBCCache

transactionRolledBack

public void transactionRolledBack()
