      String getURL()
      Returns the URL at which this SPARQL endpoint can be reached.

    • supportsMoreThanTriplePatterns

      default boolean supportsMoreThanTriplePatterns()
      Description copied from interface: FederationMember
      Returns false if the only types of graph patterns that can be answered by a single request to this federation member are triple patterns.

      Notice that a return value of true does not mean that the federation member supports arbitrary graph patterns, but only that it supports more than only triple patterns. For a more specific way of checking, use FederationMember.isSupportedPattern(SPARQLGraphPattern).
