Method Detail

setBaseSail

public void setBaseSail(Sail baseSail)

Description copied from interface: StackableSail

Sets the base Sail that this Sail will work on top of. This method will be called before the initialize() method is called.

Specified by:

setBaseSail in interface StackableSail

Overrides:

setBaseSail in class NotifyingSailWrapper

getFunctionRegistry

public FunctionRegistry getFunctionRegistry()

setFunctionRegistry

public void setFunctionRegistry(FunctionRegistry registry)

getTupleFunctionRegistry

public TupleFunctionRegistry getTupleFunctionRegistry()

setTupleFunctionRegistry

public void setTupleFunctionRegistry(TupleFunctionRegistry registry)

getFederatedServiceResolver

public FederatedServiceResolver getFederatedServiceResolver()

setFederatedServiceResolver

public void setFederatedServiceResolver(FederatedServiceResolver resolver)

Description copied from interface: FederatedServiceResolverClient

Sets the FederatedServiceResolver to use for this client.

Specified by:

setFederatedServiceResolver in interface FederatedServiceResolverClient

Overrides:

setFederatedServiceResolver in class SailWrapper

Parameters:

resolver - The resolver to use.

setEvaluationMode

public void setEvaluationMode(TupleFunctionEvaluationMode mode)

getEvaluationMode

public TupleFunctionEvaluationMode getEvaluationMode()

setAxiomClosureNeeded

public void setAxiomClosureNeeded(boolean axiomClosureNeeded)

isAxiomClosureNeeded

public boolean isAxiomClosureNeeded()

Indicates if the SPIN Sail should itself load the full deductive closure of the SPIN axioms. Typically, this will be false if the underlying Sail stack already supports RDFS inferencing, true if not.

Returns:

true if the SpinSail needs to load the full axiom closure, false otherwise.

addQueryContextInitializer

public void addQueryContextInitializer(QueryContextInitializer initializer)

getQueryContextInitializers

protected List<QueryContextInitializer> getQueryContextInitializers()

getSpinParser

public SpinParser getSpinParser()

setSpinParser

public void setSpinParser(SpinParser parser)

getConnection

public org.eclipse.rdf4j.sail.spin.SpinSailConnection getConnection()
                                                             throws SailException

Description copied from interface: Sail

Opens a connection on the Sail which can be used to query and update data. Depending on how the implementation handles concurrent access, a call to this method might block when there is another open connection on this Sail.

Specified by:

getConnection in interface NotifyingSail

Specified by:

getConnection in interface Sail

Overrides:

getConnection in class NotifyingSailWrapper

Throws:

SailException - If no transaction could be started, for example because the Sail is not writable.

initialize

public void initialize()
                throws SailException

Description copied from interface: Sail

Initializes the Sail. Care should be taken that required initialization parameters have been set before this method is called. Please consult the specific Sail implementation for information about the relevant parameters.

Specified by:

initialize in interface Sail

Overrides:

initialize in class SailWrapper

Throws:

SailException - If the Sail could not be initialized.
