expunge

@Transactional(propagation=NEVER)
public ExpungeOutcome expunge(ExpungeOptions theExpungeOptions,
 ca.uhn.fhir.rest.api.server.RequestDetails theRequestDetails)

Specified by:

expunge in interface IFhirSystemDao<T extends org.hl7.fhir.instance.model.api.IBaseBundle,MT>

getResourceCounts

@Transactional(propagation=REQUIRED)
public Map<String,Long> getResourceCounts()

Specified by:

getResourceCounts in interface IFhirSystemDao<T extends org.hl7.fhir.instance.model.api.IBaseBundle,MT>

getResourceCountsFromCache

@Nullable
public Map<String,Long> getResourceCountsFromCache()

Specified by:

getResourceCountsFromCache in interface IFhirSystemDao<T extends org.hl7.fhir.instance.model.api.IBaseBundle,MT>

history

transaction

public T transaction(ca.uhn.fhir.rest.api.server.RequestDetails theRequestDetails,
 T theRequest)

Specified by:

transaction in interface IFhirSystemDao<T extends org.hl7.fhir.instance.model.api.IBaseBundle,MT>

transactionNested

public T transactionNested(ca.uhn.fhir.rest.api.server.RequestDetails theRequestDetails,
 T theRequest)

Specified by:

transactionNested in interface IFhirSystemDao<T extends org.hl7.fhir.instance.model.api.IBaseBundle,MT>

preFetchResources

public <P extends ca.uhn.fhir.rest.api.server.storage.IResourcePersistentId>
void preFetchResources(List<P> theResolvedIds,
 boolean thePreFetchIndexes)

Prefetch entities into the Hibernate session. When processing several resources (e.g. transaction bundle, $reindex chunk, etc.) it would be slow to fetch each piece of a resource (e.g. all token index rows) one resource at a time. Instead, we fetch all the linked resources for the entire batch and populate the Hibernate Session.

Specified by:

preFetchResources in interface IFhirSystemDao<T extends org.hl7.fhir.instance.model.api.IBaseBundle,MT>

Parameters:

theResolvedIds - the pids

thePreFetchIndexes - Should resource indexes be loaded

getResourceName

@Nullable
protected String getResourceName()

Specified by:

getResourceName in class BaseStorageDao

getInterceptorBroadcaster

protected ca.uhn.fhir.interceptor.api.IInterceptorBroadcaster getInterceptorBroadcaster()

Specified by:

getStorageSettings

protected JpaStorageSettings getStorageSettings()

Specified by:

getStorageSettings in class BaseStorageDao

getContext

public ca.uhn.fhir.context.FhirContext getContext()

Specified by:

getContext in interface IDao

Specified by:

getContext in class BaseStorageDao

setStorageSettingsForUnitTest

public void setStorageSettingsForUnitTest(JpaStorageSettings theStorageSettings)
