public static interface Graph.Features.GraphFeatures extends Graph.Features.FeatureSet
Features specific to a operations of a "graph".

  • Field Details

  • Method Details

    • supportsComputer

      default boolean supportsComputer()
      Determines if the Graph implementation supports GraphComputer based processing.

    • supportsPersistence

      default boolean supportsPersistence()
      Determines if the Graph implementation supports persisting it's contents natively to disk. This feature does not refer to every graph's ability to write to disk via the Gremlin IO packages (.e.g. GraphML), unless the graph natively persists to disk via those options somehow. For example, TinkerGraph does not support this feature as it is a pure in-sideEffects graph.

    • supportsConcurrentAccess

      default boolean supportsConcurrentAccess()
      Determines if the Graph implementation supports more than one connection to the same instance at the same time.

    • supportsTransactions

      default boolean supportsTransactions()
      Determines if the Graph implementations supports transactions.

    • supportsThreadedTransactions

      default boolean supportsThreadedTransactions()
      Determines if the Graph implementation supports threaded transactions which allow a transaction to be executed across multiple threads via Transaction.createThreadedTx().

    • supportsIoRead

      default boolean supportsIoRead()
      Determines if the Graph implementations supports read operations as executed with the GraphTraversalSource.io(String) step. Graph implementations will generally support this by default as any graph that can support direct mutation through the Structure API will by default accept data from the standard TinkerPop GraphReader implementations. However, some graphs like HadoopGraph don't accept direct mutations but can still do reads from that io() step.

    • supportsIoWrite

      default boolean supportsIoWrite()
      Determines if the Graph implementations supports write operations as executed with the GraphTraversalSource.io(String) step. Graph implementations will generally support this by default given the standard TinkerPop GraphWriter implementations. However, some graphs like HadoopGraph will use a different approach to handle writes.

    • supportsOrderabilitySemantics

      default boolean supportsOrderabilitySemantics()
      Determines if the Graph implementation supports total universal orderability per the Gremlin orderability semantics.

    • supportsServiceCall

      default boolean supportsServiceCall()
      Determines if the Graph implementation supports the service call feature.

    • variables

      default Graph.Features.VariableFeatures variables()
      Gets the features related to "graph sideEffects" operation.
