Deprecated.

@Deprecated
public class SpinSail
extends AbstractForwardChainingInferencer

The SpinSail is currently deprecated. If you are using SPIN to validate your data then it is recommended to move to SHACL with the ShaclSail. Currently, the SHACL W3C Recommendation only supports validation, and has no equivalent to SPIN's inference features.

Deprecating the SpinSail has been discussed at https://github.com/eclipse/rdf4j/issues/1262 and can be summarized with there being no developers actively supporting it and that SPIN in itself is no longer recommended by TopQuadrant. Do not expect the SpinSail to scale in any way and expect simple delete operations to take seconds to complete. There are still a number of open issues in GitHub connected to the SpinSail, none of these are likely to get fixed.

Since:

3.1.0 2019

SpinSail

public SpinSail(org.eclipse.rdf4j.sail.NotifyingSail baseSail)

Deprecated.

Method Detail

setBaseSail

public void setBaseSail(org.eclipse.rdf4j.sail.Sail baseSail)

Deprecated.

Specified by:

setBaseSail in interface org.eclipse.rdf4j.sail.StackableSail

Overrides:

setBaseSail in class org.eclipse.rdf4j.sail.helpers.NotifyingSailWrapper

getFunctionRegistry

public org.eclipse.rdf4j.query.algebra.evaluation.function.FunctionRegistry getFunctionRegistry()

Deprecated.

setFunctionRegistry

public void setFunctionRegistry(org.eclipse.rdf4j.query.algebra.evaluation.function.FunctionRegistry registry)

Deprecated.

getTupleFunctionRegistry

public org.eclipse.rdf4j.query.algebra.evaluation.function.TupleFunctionRegistry getTupleFunctionRegistry()

Deprecated.

setTupleFunctionRegistry

public void setTupleFunctionRegistry(org.eclipse.rdf4j.query.algebra.evaluation.function.TupleFunctionRegistry registry)

Deprecated.

getFederatedServiceResolver

public org.eclipse.rdf4j.query.algebra.evaluation.federation.FederatedServiceResolver getFederatedServiceResolver()

Deprecated.

setFederatedServiceResolver

public void setFederatedServiceResolver(org.eclipse.rdf4j.query.algebra.evaluation.federation.FederatedServiceResolver resolver)

Deprecated.

Specified by:

setFederatedServiceResolver in interface org.eclipse.rdf4j.query.algebra.evaluation.federation.FederatedServiceResolverClient

Overrides:

setFederatedServiceResolver in class org.eclipse.rdf4j.sail.helpers.SailWrapper

setEvaluationMode

public void setEvaluationMode(TupleFunctionEvaluationMode mode)

Deprecated.

getEvaluationMode

public TupleFunctionEvaluationMode getEvaluationMode()

Deprecated.

setAxiomClosureNeeded

public void setAxiomClosureNeeded(boolean axiomClosureNeeded)

Deprecated.

isAxiomClosureNeeded

public boolean isAxiomClosureNeeded()

Deprecated.

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(org.eclipse.rdf4j.query.algebra.evaluation.QueryContextInitializer initializer)

Deprecated.

getQueryContextInitializers

protected List<org.eclipse.rdf4j.query.algebra.evaluation.QueryContextInitializer> getQueryContextInitializers()

Deprecated.

getSpinParser

public SpinParser getSpinParser()

Deprecated.

setSpinParser

public void setSpinParser(SpinParser parser)

Deprecated.

getConnection

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

Deprecated.

Specified by:

getConnection in interface org.eclipse.rdf4j.sail.NotifyingSail

Specified by:

getConnection in interface org.eclipse.rdf4j.sail.Sail

Overrides:

getConnection in class org.eclipse.rdf4j.sail.helpers.NotifyingSailWrapper

Throws:

org.eclipse.rdf4j.sail.SailException

Overrides:

initialize in class org.eclipse.rdf4j.sail.helpers.SailWrapper

Throws:

org.eclipse.rdf4j.sail.SailException

isInitializing

public boolean isInitializing()

Deprecated.

public void setValidateConstraints(boolean validateConstraints)

Deprecated.

Disable or enable SPIN constraint validation. This can be very useful in order to improve performance

Default true (constraint validation enabled).

Parameters:

validateConstraints - (true if enabled)

isValidateConstraints

public boolean isValidateConstraints()

Deprecated.

Check is SPIN constraint validation is enabled.

Returns:

true if enabled
