StructuralReasoner

public StructuralReasoner(OWLOntology rootOntology,
                          OWLReasonerConfiguration configuration,
                          BufferingMode bufferingMode)

Parameters:

rootOntology - the ontology

configuration - the reasoner configuration

bufferingMode - the buffering mode

Method Detail

getReasonerName

public String getReasonerName()

Description copied from interface: OWLReasoner

Gets the name of this reasoner.

Returns:

A string that represents the name of this reasoner.

getFreshEntityPolicy

public FreshEntityPolicy getFreshEntityPolicy()

Description copied from interface: OWLReasoner

Gets the Fresh Entity Policy in use by this reasoner. The policy is set at reasoner creation time.

Specified by:

getFreshEntityPolicy in interface OWLReasoner

Overrides:

getFreshEntityPolicy in class OWLReasonerBase

Returns:

The policy.

getIndividualNodeSetPolicy

public IndividualNodeSetPolicy getIndividualNodeSetPolicy()

Description copied from interface: OWLReasoner

Gets the IndividualNodeSetPolicy in use by this reasoner. The policy is set at reasoner creation time.

Specified by:

getIndividualNodeSetPolicy in interface OWLReasoner

Overrides:

getIndividualNodeSetPolicy in class OWLReasonerBase

Returns:

The policy.

getReasonerVersion

public Version getReasonerVersion()

Description copied from interface: OWLReasoner

Gets the version of this reasoner.

Returns:

The version of this reasoner. Not null.

handleChanges

protected void handleChanges(Set<OWLAxiom> addAxioms,
                             Set<OWLAxiom> removeAxioms)

Description copied from class: OWLReasonerBase

Asks the reasoner implementation to handle axiom additions and removals from the imports closure of the root ontology. The changes will not include annotation axiom additions and removals.

Specified by:

handleChanges in class OWLReasonerBase

Parameters:

addAxioms - The axioms to be added to the reasoner.

removeAxioms - The axioms to be removed from the reasoner

interrupt

public void interrupt()

Description copied from interface: OWLReasoner

Asks the reasoner to interrupt what it is currently doing. An ReasonerInterruptedException will be thrown in the thread that invoked the last reasoner operation. The OWL API is not thread safe in general, but it is likely that this method will be called from another thread than the event dispatch thread or the thread in which reasoning takes place.
Note that the reasoner will periodically check for interupt requests. Asking the reasoner to interrupt the current process does not mean that it will be interrupted immediately. However, clients can expect to be able to interupt individual consistency checks, satisfiability checks etc.

prepareReasoner

public void prepareReasoner()
                     throws ReasonerInterruptedException,
                            TimeOutException

Throws:

ReasonerInterruptedException - on interruption

TimeOutException - on timeout

precomputeInferences

public void precomputeInferences(InferenceType... inferenceTypes)
                          throws ReasonerInterruptedException,
                                 TimeOutException,
                                 InconsistentOntologyException

Description copied from interface: OWLReasoner

Asks the reasoner to precompute certain types of inferences. Note that it is NOT necessary to call this method before asking any other queries - the reasoner will answer all queries correctly regardless of whether inferences are precomputed or not. For example, if the imports closure of the root ontology entails SubClassOf(A B) then the result of getSubClasses(B) will contain A, regardless of whether precomputeInferences( InferenceType#CLASS_HIERARCHY) has been called.
If the reasoner does not support the precomputation of a particular type of inference then it will silently ignore the request.

Parameters:

inferenceTypes - Suggests a list of the types of inferences that should be precomputed. If the list is empty then the reasoner will determine which types of inferences are precomputed. Note that the order of the list is unimportant - the reasoner will determine the order in which inferences are computed.

Throws:

ReasonerInterruptedException - if the reasoning process was interrupted for any particular reason (for example if reasoning was cancelled by a client process)

TimeOutException - if the reasoner timed out during a basic reasoning operation. See OWLReasoner.getTimeOut().

InconsistentOntologyException - if the imports closure of the root ontology is inconsistent

isPrecomputed

public boolean isPrecomputed(InferenceType inferenceType)

Description copied from interface: OWLReasoner

Determines if a specific set of inferences have been precomputed.

inferenceType - The type of inference to check for.

Returns:

true if the specified type of inferences have been precomputed, otherwise false.

public Set<InferenceType> getPrecomputableInferenceTypes()

Description copied from interface: OWLReasoner

Returns the set of InferenceTypes that are precomputable by reasoner.

Returns:

A set of InferenceTypes that can be precomputed by this reasoner.

Description copied from interface: OWLReasoner

Determines if the set of reasoner axioms is consistent. Note that this method will NOT throw an InconsistentOntologyException even if the root ontology imports closure is inconsistent.

Returns:

true if the imports closure of the root ontology is consistent, or false if the imports closure of the root ontology is inconsistent.

Throws:

ReasonerInterruptedException - if the reasoning process was interrupted for any particular reason (for example if reasoning was cancelled by a client process).

Description copied from interface: OWLReasoner

Gets the individuals which are instances of the specified class expression. The individuals are returned a a NodeSet.

Parameters:

ce - The class expression whose instances are to be retrieved.

direct - Specifies if the direct instances should be retrieved ( true), or if all instances should be retrieved ( false).

Returns:

If direct is true, a NodeSet containing named individuals such that for each named individual j in the node set, the set of reasoner axioms entails DirectClassAssertion(ce, j).
If direct is false, a NodeSet containing named individuals such that for each named individual j in the node set, the set of reasoner axioms entails ClassAssertion(ce, j).
If ce is unsatisfiable with respect to the set of reasoner axioms then the empty NodeSet is returned.

Throws:

InconsistentOntologyException - if the imports closure of the root ontology is inconsistent

ClassExpressionNotInProfileException - if the class expression ce is not in the profile that is supported by this reasoner.

FreshEntitiesException - if the signature of the class expression is not contained within the signature of the imports closure of the root ontology and the undeclared entity policy of this reasoner is set to FreshEntityPolicy.DISALLOW.

ReasonerInterruptedException - if the reasoning process was interrupted for any particular reason (for example if reasoning was cancelled by a client process)

TimeOutException - if the reasoner timed out during a basic reasoning operation. See OWLReasoner.getTimeOut().

                                             TimeOutException

Description copied from interface: OWLReasoner

Gets the data property values for the specified individual and data property expression. The values are a set of literals. Note that the results are not guaranteed to be complete for this method. The reasoner may also return canonical literals or they may be in a form that bears a resemblance to the syntax of the literals in the root ontology imports closure.

Parameters:

ind - The individual that is the subject of the data property values

pe - The data property expression whose values are to be retrieved for the specified individual

Returns:

A set of OWLLiterals containing literals such that for each literal l in the set, the set of reasoner axioms entails DataPropertyAssertion(pe ind l).

Throws:

InconsistentOntologyException - if the imports closure of the root ontology is inconsistent

FreshEntitiesException - if the signature of the individual and property expression is not contained within the signature of the imports closure of the root ontology and the undeclared entity policy of this reasoner is set to FreshEntityPolicy.DISALLOW.

ReasonerInterruptedException - if the reasoning process was interrupted for any particular reason (for example if reasoning was cancelled by a client process)

Description copied from interface: OWLReasoner

Gets the individuals that are the same as the specified individual.

Parameters:

Throws:

InconsistentOntologyException - if the imports closure of the root ontology is inconsistent
