- - ### Method Detail

    - #### setComputer

          void setComputer(Computer computer)

      Set the `Computer` to be used to generate the `GraphComputer`.
      Parameters:
        `computer` - the computer specification.

    - #### getComputer

          Computer getComputer()

      Get the `Computer` for generating the `GraphComputer`. Inferences on the state of the `Step` within the `Traversal` can be use applied here.
      Returns:
        the computer specification for generating the graph computer.

    - #### generateProgram

          VertexProgram generateProgram(Graph graph,
                                        Memory memory)

      Generate the `VertexProgram`.
      Parameters:
        `graph` - the `Graph` that the program will be executed over.
        `memory` - the `Memory` from the previous OLAP job if it exists, else its an empty memory structure.
      Returns:
        the generated vertex program instance.
