Method Detail

createStartEntry

protected CHEntry createStartEntry(int node,
                                   double weight,
                                   boolean reverse)

Description copied from class: AbstractBidirAlgo

Creates the root shortest path tree entry for the forward or backward search.

Specified by:

createStartEntry in class AbstractBidirAlgo

createEntry

protected CHEntry createEntry(int edge,
                              int adjNode,
                              int incEdge,
                              double weight,
                              SPTEntry parent,
                              boolean reverse)

Description copied from class: AbstractBidirCHAlgo

Creates a new entry of the shortest path tree (a SPTEntry or one of its subclasses) during a dijkstra expansion.

Specified by:

createEntry in class AbstractBidirCHAlgo

Parameters:

edge - the id of the edge that is currently processed for the expansion

adjNode - the adjacent node of the edge

incEdge - the id of the edge that is incoming to the node the edge is pointed at. usually this is the same as edge, but for edge-based CH and in case edge corresponds to a shortcut incEdge is the original edge that is incoming to the node

weight - the weight the shortest path three entry should carry

parent - the parent entry of in the shortest path tree

reverse - true if we are currently looking at the backward search, false otherwise

updateEntry

protected void updateEntry(SPTEntry entry,
                           int edge,
                           int adjNode,
                           int incEdge,
                           double weight,
                           SPTEntry parent,
                           boolean reverse)

Overrides:

updateEntry in class AbstractBidirCHAlgo

getName

public String getName()

Specified by:

getName in interface RoutingAlgorithm

Overrides:

getName in class AbstractBidirAlgo

Returns:

name of this algorithm
