    • Method Detail

      • isConsistent

        boolean isConsistent()
              throws StardogException
        Checks the consistency of the database with the current reasoning flag. If the consistency check has been performed before and the database has not changed this function will return the previously computed result immediately. Besides this caching functionality, this function always returns the same result as the isConsistent(ContextSets.LOCAL) call.
        Returns:
        true if the database is consistent, false otherwise
        Throws:
        StardogException

      • isConsistent

        boolean isConsistent​(java.util.Collection<IRI> theActiveGraphs)
              throws StardogException
        Checks the consistency of the specified named graphs with the current reasoning flag. The consistency results for arbitrary set of named graphs are not cached so this function will perform a new consistency check over at each invocation.
        Returns:
        true if the database is consistent, false otherwise
        Throws:
        StardogException

      • isSatisfiable

        boolean isSatisfiable​(IRI theClass)
               throws StardogException
        Checks whether the class is satisfiable with respect to the current KB and reasoning flag
        Parameters:
        theClass - the class
        Returns:
        true if the class is satisfiable, false otherwise
        Throws:
        StardogException

      • getUnsatisfiableClasses

        java.util.Collection<IRI> getUnsatisfiableClasses()
                                           throws StardogException
        Returns the collection of unsatisfiable classes in the current KB.
        Throws:
        StardogException

      • getObjectProperties

        java.util.Collection<IRI> getObjectProperties()
                                       throws StardogException
        Returns the collection of object properties in the current KB.
        Returns:
        the object properties
        Throws:
        StardogException - if there was an error obtaining the properties

      • getDataProperties

        java.util.Collection<IRI> getDataProperties()
                                     throws StardogException
        Returns the collection of data properties in the current KB.
        Returns:
        the data properties
        Throws:
        StardogException - if there was an error obtaining the properties

      • explain

        StardogExplainer explain​(Statement theStmt)
        Returns a explainer that can be used to explain why the given statement is inferred.
        Parameters:
        theStmt - the statement to be explained
        Returns:
        An explainer for the inference.

      • explain

        StardogExplainer explain​(Axiom theExpr)
        Returns a explainer that can be used to explain why the given expression is inferred.
        Parameters:
        theExpr - the expression to be explained
        Returns:
        An explainer for the inference.

      • explainInconsistency

        StardogExplainer explainInconsistency()
        Returns a explainer that can be used to explain why the given statement is inferred.
        Returns:
        An explainer for inconsistency.

      • getSchemaManager

        SchemaManager getSchemaManager()
        Returns the schema manager for the database
        Returns:
        the schema manager for the database
