      public static LogicalGraph newLogicalGraph()
      Creates an empty logical graph. The graph is assigned a default name of "root".
      Returns:
      a new logical graph ready for defining contained operators

    • newLogicalGraph

      public static LogicalGraph newLogicalGraph(String name)
      Creates an empty logical graph with a specified name.
      Parameters:
      name - name of the graph, not necessarily unique
      Returns:
      a new logical graph ready for defining contained operators

      public static LogicalGraph newLogicalGraph(OperatorSettings settings, EngineConfig defaultConfig)
      Creates an empty logical graph with specified OperatorSettings and default EngineConfig. For advanced usage only; clients should generally prefer newLogicalGraph() or newLogicalGraph(String).
      Parameters:
      settings - the operator settings
      defaultConfig - the EngineConfig that will be used when the graph is compiled or run without specifying an overriding EngineConfig
      Returns:
