Method Details
- query
  
  public Boolean query(DlBeliefSet kb, DlAxiom formula)
  
  Description copied from interface: QualitativeReasoner
  
  Queries the given belief base with the provided formula and returns a boolean result. The result indicates whether the formula is entailed or satisfied by the belief base according to the qualitative reasoning method implemented by the reasoner.
  
  Specified by:
  
  query in interface QualitativeReasoner<DlBeliefSet,DlAxiom>
  
  Specified by:
  
  query in interface Reasoner<Boolean,DlBeliefSet,DlAxiom>
  
  Parameters:
  
  kb - The belief base to be queried.
  
  formula - The formula for which the query is made.
  
  Returns:
  
  `TRUE` if the formula is entailed or satisfied by the belief base, `FALSE` otherwise.
- getAllInterpretations
  
  public Set<DlInterpretation> getAllInterpretations(DlSignature sig)
  
  Get all interpretations for the given signature.
  
  Parameters:
  
  sig - a DLSignature
  
  Returns:
  
  set of all interpretations
- isInstalled
  
  public boolean isInstalled()
  
  the solver is natively installed and is therefore always installed
  
  Specified by:
  
  isInstalled in interface QualitativeReasoner<DlBeliefSet,DlAxiom>
  
  Returns:
  
  `true` if the solver is installed and available, `false` otherwise.
