Method Details

getPreviousStateConnection

public SailConnection getPreviousStateConnection()

hasPreviousStateConnection

public boolean hasPreviousStateConnection()

getAddedStatements

public SailConnection getAddedStatements()

getRemovedStatements

public SailConnection getRemovedStatements()

getSailSpecificValue

public <T extends Value> T getSailSpecificValue(T value,
 ConnectionsGroup.StatementPosition statementPosition,
 SailConnection connection)

This method is a performance optimization for converting a more general value object, like RDF.TYPE, to the specific Value object that the underlying sail would use for that node. It uses a cache to avoid querying the store for the same value multiple times during the same validation.

Type Parameters:

T - the type of the value

Parameters:

value - the value object to be converted

statementPosition - the position of the statement (subject, predicate, or object)

connection - the SailConnection used to retrieve the specific Value object

Returns:

the specific Value object used by the underlying sail, or the original value if no specific Value is found

Throws:

SailException - if an error occurs while retrieving the specific Value object

close

public void close()

Specified by:

close in interface AutoCloseable

getBaseConnection

public SailConnection getBaseConnection()

getCachedNodeFor

public PlanNode getCachedNodeFor(PlanNode planNode)

getRdfsSubClassOfReasoner

public RdfsSubClassOfReasoner getRdfsSubClassOfReasoner()

Returns the RdfsSubClassOfReasoner if it is enabled. If it is not enabled this method will return null.

Returns:

RdfsSubClassOfReasoner or null

getStats

public Stats getStats()

getTransactionSettings

public ShaclSailConnection.Settings getTransactionSettings()

isSparqlValidation

public boolean isSparqlValidation()

hasAddedStatements

public boolean hasAddedStatements()
