A handler doing "something" on a link graph component.
Calculate the demands.
Definition: demands.h:12
void CalcDemand(LinkGraphJob &job, Tscaler scaler)
Do the actual demand calculation, called from constructor.
Definition: demands.cpp:165
DemandCalculator(LinkGraphJob &job)
Create the DemandCalculator and immediately do the calculation.
Definition: demands.cpp:262
int32_t base_distance
Base distance for scaling purposes.
Definition: demands.h:17
int32_t mod_dist
Distance modifier, determines how much demands decrease with distance.
Definition: demands.h:18
int32_t accuracy
Accuracy of the calculation.
Definition: demands.h:19
Stateless, thread safe demand handler.
Definition: demands.h:28
virtual ~DemandHandler()=default
Virtual destructor has to be defined because of virtual Run().
void Run(LinkGraphJob &job) const override
Call the demand calculator on the given component.
Definition: demands.h:35
Class for calculation jobs to be run on link graphs.
Definition: linkgraphjob.h:29
Some typedefs for component handlers.
