    Specified by:
    
    getReasonerName in interface org.semanticweb.owlapi.reasoner.OWLReasoner
  - getReasonerVersion
```
public org.semanticweb.owlapi.util.Version getReasonerVersion()
```
    Specified by:

  - getBufferingMode
```
public org.semanticweb.owlapi.reasoner.BufferingMode getBufferingMode()
```
    Specified by:
    
    getBufferingMode in interface org.semanticweb.owlapi.reasoner.OWLReasoner
  - flush
```
public void flush()
```
    Classifies the ontology incrementally if no import changes have occurred. Flushes any changes stored in the buffer, which causes the reasoner to take into consideration the changes the current root ontology specified by the changes. If the reasoner buffering mode is BufferingMode.NON_BUFFERING then this method will have no effect.
    
    Specified by:
    
    flush in interface org.semanticweb.owlapi.reasoner.OWLReasoner
  - getPendingChanges
```
public List<org.semanticweb.owlapi.model.OWLOntologyChange> getPendingChanges()
```
    Gets the pending changes which need to be taken into consideration by the reasoner so that it is up to date with the root ontology imports closure. After the flush() method is called the set of pending changes will be empty.
    
    Specified by:
    
    getPendingChanges in interface org.semanticweb.owlapi.reasoner.OWLReasoner
    
    Returns:
    
    A set of changes. Note that the changes represent the raw changes as applied to the imports closure of the root ontology.
  - getPendingAxiomAdditions
```
public Set<org.semanticweb.owlapi.model.OWLAxiom> getPendingAxiomAdditions()
```
    Gets the axioms that as a result of ontology changes need to be added to the reasoner to synchronise it with the root ontology imports closure. If the buffering mode is BufferingMode.NON_BUFFERING then there will be no pending axiom additions.
    
    Specified by:
    
    getPendingAxiomAdditions in interface org.semanticweb.owlapi.reasoner.OWLReasoner
    
    Returns:
    
    The set of axioms that need to added to the reasoner to the reasoner to synchronise it with the root ontology imports closure.
  - getPendingAxiomRemovals
```
public Set<org.semanticweb.owlapi.model.OWLAxiom> getPendingAxiomRemovals()
```
    Gets the axioms that as a result of ontology changes need to removed to the reasoner to synchronise it with the root ontology imports closure. If the buffering mode is BufferingMode.NON_BUFFERING then there will be no pending axiom additions.
    
    Specified by:
    
    getPendingAxiomRemovals in interface org.semanticweb.owlapi.reasoner.OWLReasoner
    
    Returns:
    
    The set of axioms that need to added to the reasoner to the reasoner to synchronise it with the root ontology imports closure.
  - getRootOntology
```
public org.semanticweb.owlapi.model.OWLOntology getRootOntology()
```
    Gets the "root" ontology that is loaded into this reasoner. The reasoner takes into account the axioms in this ontology and its imports closure, plus the axioms returned by getPendingAxiomRemovals(), minus the axioms returned by getPendingAxiomAdditions() when reasoning.
    Note that the root ontology is set at reasoner creation time and cannot be changed thereafter. Clients that want to add ontologies to and remove ontologies from the reasoner after creation time should create a "dummy" ontology that imports the "real" ontologies and then specify the dummy ontology as the root ontology at reasoner creation time.
    
    Specified by:
    
    getRootOntology in interface org.semanticweb.owlapi.reasoner.OWLReasoner
    
    Returns:
    
    The root ontology that is loaded into the reasoner.
  - interrupt
```
public void interrupt()
```
    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 interrupt 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 interrupt individual consistency checks, satisfiability checks etc.
    
    Specified by:
    
    interrupt in interface org.semanticweb.owlapi.reasoner.OWLReasoner
  - precomputeInferences
```
public void precomputeInferences(org.semanticweb.owlapi.reasoner.InferenceType... inferenceTypes)
                          throws org.semanticweb.owlapi.reasoner.ReasonerInterruptedException,
                                 org.semanticweb.owlapi.reasoner.TimeOutException,
                                 org.semanticweb.owlapi.reasoner.InconsistentOntologyException
```
    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.
    
    Specified by:
    
    precomputeInferences in interface org.semanticweb.owlapi.reasoner.OWLReasoner
    
    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:
    
    org.semanticweb.owlapi.reasoner.InconsistentOntologyException - if the imports closure of the root ontology is inconsistent
    
    org.semanticweb.owlapi.reasoner.ReasonerInterruptedException - if the reasoning process was interrupted for any particular reason (for example if reasoning was cancelled by a client process)
    
    org.semanticweb.owlapi.reasoner.TimeOutException - if the reasoner timed out during a basic reasoning operation. See getTimeOut().
  - isPrecomputed
```
public boolean isPrecomputed(org.semanticweb.owlapi.reasoner.InferenceType inferenceType)
```
    Determines if a specific set of inferences have been precomputed.
    
    Specified by:
    
    isPrecomputed in interface org.semanticweb.owlapi.reasoner.OWLReasoner
    
    Parameters:
    
    inferenceType - The type of inference to check for.
    
    Returns:
    
    true if the specified type of inferences have been precomputed, otherwise false.
  - getPrecomputableInferenceTypes
```
public Set<org.semanticweb.owlapi.reasoner.InferenceType> getPrecomputableInferenceTypes()
```
    Returns the set of InferenceTypes that are precomputable by reasoner.
    
    Specified by:
    
    getPrecomputableInferenceTypes in interface org.semanticweb.owlapi.reasoner.OWLReasoner
    
    Returns:
    
    A set of InferenceTypes that can be precomputed by this reasoner.
  - isConsistent
```
public boolean isConsistent()
                     throws org.semanticweb.owlapi.reasoner.ReasonerInterruptedException,
                            org.semanticweb.owlapi.reasoner.TimeOutException
```
    Inconsistent Ontology - this occurs when the axioms in an ontology contain a contradiction which prevents the ontology from having a model, e.g., when the ontology asserts that an individual belongs to an unsatisfiable concept. Snorocket does not currently support individuals so this method always returns true. TODO: if there is a syntactic issue such as a datatype being declared with a literal value of a different type than the one declared in a restriction, should this method return false? 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.
    
    Specified by:
    
    isConsistent in interface org.semanticweb.owlapi.reasoner.OWLReasoner
    
    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:
    
    org.semanticweb.owlapi.reasoner.ReasonerInterruptedException - if the reasoning process was interrupted for any particular reason (for example if reasoning was cancelled by a client process).
    
    org.semanticweb.owlapi.reasoner.TimeOutException - if the reasoner timed out during a basic reasoning operation. See getTimeOut().

    Parameters:
    
    classExpression - The class expression
    
    Returns:
    
    true if classExpression is satisfiable with respect to the set of axioms, or false if classExpression is unsatisfiable with respect to the axioms.
    
    Throws:

    Gets the individuals which are entailed to be different from the specified individual. The individuals are returned as a NodeSet.
    
    Specified by:
    
    getDifferentIndividuals in interface org.semanticweb.owlapi.reasoner.OWLReasoner
    
    Parameters:
    
    ind - The individual whose different individuals are to be returned.
    
    Returns:
    
    A NodeSet containing OWLNamedIndividual s such that for each individual i in the NodeSet the set of reasoner axioms entails DifferentIndividuals(ind, i).
    
    Throws:

  - getTimeOut
```
public long getTimeOut()
```
    Gets the time out (in milliseconds) for the most basic reasoning operations. That is the maximum time for a satisfiability test, subsumption test etc. The time out should be set at reasoner creation time. During satisfiability (subsumption) checking the reasoner will check to see if the time it has spent doing the single check is longer than the value returned by this method. If this is the case, the reasoner will throw a TimeOutException in the thread that is executing the reasoning process.
    Note that clients that want a higher level timeout, at the level of classification for example, should start their own timers and request that the reasoner interrupts the current process using the interrupt() method.
    
    Specified by:
    
    getTimeOut in interface org.semanticweb.owlapi.reasoner.OWLReasoner
    
    Returns:
    
    The time out in milliseconds for basic reasoner operation. By default this is the value of Long.MAX_VALUE.

```
    Gets the Fresh Entity Policy in use by this reasoner. The policy is set at reasoner creation time.
    
    Specified by:
    
    getFreshEntityPolicy in interface org.semanticweb.owlapi.reasoner.OWLReasoner
    
    Returns:
    
    The policy.
  - getIndividualNodeSetPolicy
```
public org.semanticweb.owlapi.reasoner.IndividualNodeSetPolicy getIndividualNodeSetPolicy()
```
    Gets the IndividualNodeSetPolicy in use by this reasoner. The policy is set at reasoner creation time.
    
    Specified by:
    
    getIndividualNodeSetPolicy in interface org.semanticweb.owlapi.reasoner.OWLReasoner
    
    Returns:
    
    The policy.
  - dispose
```
public void dispose()
```
    Disposes of this reasoner. This frees up any resources used by the reasoner and detaches the reasoner as an OWLOntologyChangeListener from the OWLOntologyManager that manages the ontologies contained within the reasoner.
    
    Specified by:
    
    dispose in interface org.semanticweb.owlapi.reasoner.OWLReasoner
