Method Detail

program

public GraphComputer program(VertexProgram vertexProgram)

Description copied from interface: GraphComputer

Set the VertexProgram to be executed by the GraphComputer. There can only be one VertexProgram for the GraphComputer.

Specified by:

program in interface GraphComputer

Overrides:

program in class AbstractHadoopGraphComputer

Parameters:

vertexProgram - the VertexProgram to be executed

Returns:

the updated GraphComputer with newly set VertexProgram

submit

public Future<ComputerResult> submit()

Description copied from interface: GraphComputer

Submit the VertexProgram and the set of MapReduce jobs for execution by the GraphComputer.

Specified by:

submit in interface GraphComputer

Returns:

a Future denoting a reference to the asynchronous computation and where to get the DefaultComputerResult when its is complete.
