MSRouteLoaderControl Class Reference

#include <MSRouteLoaderControl.h>

Detailed Description

MSRouteLoaderControl This controls is initialised with the list of route loaders and uses them to load routes step wise. The parameter myInAdvanceStepNo holds the number of time steps to read the routes in forward. If it is 0 (default), all routes will be read at once.
