reset()

void org.matsim.pt.analysis.RouteTimeDiagram.reset

(

final int

iteration

)

Gives the event handler the possibility to clean up its internal state. Within a Controler-Simulation, this is called before the mobsim starts.

Parameters

iteration

the up-coming iteration from which up-coming events will be from.

Implements org.matsim.core.events.handler.EventHandler.
