    - #### supportsDirectObjects

          public boolean supportsDirectObjects()

      Description copied from interface: `GraphComputer.Features`
      Supports `VertexProgram` and `MapReduce` parameters to be direct referenced Java objects (no serialization required). This is typically true for single machine graph computer engines. For cluster oriented graph computers, this is typically false.
