      Description copied from interface: `TripleSource`
      Gets all statements that have a specific subject, predicate and/or object. All three parameters may be null to indicate wildcards. Optionally a (set of) context(s) may be specified in which case the result will be restricted to statements matching one or more of the specified contexts.
      Specified by:
        `getStatements` in interface `TripleSource`
      Parameters:
        `subj` - A Resource specifying the subject, or null for a wildcard.
        `pred` - A URI specifying the predicate, or null for a wildcard.
        `obj` - A Value specifying the object, or null for a wildcard.
        `contexts` - The context(s) to get the statements from. Note that this parameter is a vararg and as such is optional. If no contexts are supplied the method operates on the entire repository.
      Returns:
        An iterator over the relevant statements.
      Throws:
        `QueryEvaluationException` - If the triple source failed to get the statements.

    - #### getValueFactory

          public ValueFactory getValueFactory()

      Description copied from interface: `TripleSource`
      Gets a ValueFactory object that can be used to create URI-, blank node- and literal objects.
      Specified by:
        `getValueFactory` in interface `TripleSource`
      Returns:
        a ValueFactory object for this TripleSource.
