    - #### getNamespaces

          Map<String,​String> getNamespaces()
                                          throws QueryEvaluationException

      Retrieves relevant namespaces from the query result.
      The contents of the Map may be modified after it is returned, as the initial return may be performed when the first RDF Statement is encountered.
      Returns:
        a Map<String, String> object containing (prefix, namespace) pairs.
      Throws:
        `QueryEvaluationException`
