    - #### getNamespaces

          public Map<String,String> getNamespaces()

      Description copied from interface: `GraphQueryResult`
      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.
      Specified by:
        `getNamespaces` in interface `GraphQueryResult`
      Returns:
        a Map<String, String> object containing (prefix, namespace) pairs.
