getStates

public java.util.List<State> getStates()
                                throws java.io.IOException

Returns the list of states for all the ticks and users in the simulation as specified in config.properties

getNextScheduleItem

private ScheduleItem getNextScheduleItem(java.util.ArrayList<ScheduleItem> scheduleItems,
                                         int tick,

                                  throws java.io.IOException

Contains logic for calculating the next train to board given a list of trains leaving from the current station

Parameters:

scheduleItems - A list of all trains departing from a given station throughout the day

tick - The current tick for which we require a departing train

previousStation - The station from which the user just arrived, to avoid the case where the user goes back to the same station

Returns:

ScheduleItem One element of the scheduleItems based on the logic of the function
