Constructor Detail

EventSimulation

public EventSimulation(Printer printer,
                       int duration,
                       int minJobInterval,
                       int maxJobInterval,
                       int minPages,
                       int maxPages)

Creates a new simulation to run. Takes a printer and duration to run. Generates a series of sample print jobs with a random amount of time between each job. These jobs are generated with a random amount of time between them (minJobInterval <= random time <= maxJobInterval) and a random number of pages (minPages <= random pages <= maxPages).

Parameters:

printer - The printer to test.

duration - The time (in seconds) at which to stop assuming the sim starts at time 0.

minJobInterval - The minimum amout of (random) time that should occur between two consecutive print requests.

maxJobInterval - The maximum amount of time between 2 requests.

minPages - The minimum number of pages a randomly-generated job should have.

maxPages - The maximum number of pages a job should have.

Method Detail

run

public void run()
         throws SimulationHiccupException

Runs this printer simulation. Generates and stores statistics.

Throws:

SimulationHiccupException - If something goes wrong during the sim

printStatistics

public void printStatistics()

toString

public String toString()

Provides a snapshot of the current simulation, including the current job and front parts of the event queue and delayed jobs queue.

Overrides:

main

public static void main(String[] args)

Creates a new simulation, runs it, and print the results to the screen.
