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.
