                                           ACyclicSubGraph odDag,
                                           PasManager pasManager,
                                           boolean logNewPass)

Factory method for bush initialiser

Parameters:

bush - to use

odDag - to use

pasManager - to use

logNewPass - when true new pass are logged, when false not

Returns:

created helper

executeOdBushInitialisation

public void executeOdBushInitialisation(DirectedVertex originVertex,
                                        Double oDDemandPcuH,
                                        Iterator<DirectedVertex> vertexIter,
                                        BushFlowLabel entryExitLabel)

Execute the initialisation by ensuring the correct flow is added to the bush for the given od dag and it related demand.

Parameters:

originVertex - to start with, expected to be the centroid of the od's origin. It is expected the iterator proceeds in downstream direction until reaching the destination

oDDemandPcuH - to use for the origin vertex

vertexIter - flag indicating if new pass are to be logged

entryExitLabel - to use
