Class sim.scheduler

java.lang.Object
   |
   +----sim.scheduler

public class scheduler

extends Object

provides basic scheduling functions Note: all methods and data in this class are static

clock

global simulated time

current

reference to current process

scheduler()

activate(process)

like activate(p, 0);

activate(process, int)

if p is not running or scheduled, schedule it with delay time; otherwise, do nothing

fatal_error(String)

signal a fatal error and die

hold(int)

schedule for activation after 'delay' time units, and passivate

pass_baton(process)

pass_baton() to support coroutines

pass_baton(process, boolean)

pass baton to next process

passivate()

make current process non-active

reactivate(process)

like reactivate(p, 0);

reactivate(process, int)

if p is not running or scheduled, schedule it with delay t; if p is running or scheduled, reschedule it with delay t

run_simulation()

start simulation (event queue must be non-empty)

  public static int clock

global simulated time

  public static process current

reference to current process

  public scheduler()

  public static void fatal_error(String s)

signal a fatal error and die

  public static void hold(int delay)

schedule for activation after 'delay' time units, and passivate @param delay time for which to hold

  public static void passivate()

make current process non-active

  public static void activate(process p)

like activate(p, 0);

  public static void activate(process p,
                              int time)

if p is not running or scheduled, schedule it with delay time; otherwise, do nothing

Parameters:

p - process to be activated

time - time after which to schedule p

  public static void reactivate(process p)

like reactivate(p, 0);

  public static void reactivate(process p,
                                int t)

if p is not running or scheduled, schedule it with delay t; if p is running or scheduled, reschedule it with delay t

Parameters:

p - process to be activated

t - time after which to activate p

  public static void run_simulation()

start simulation (event queue must be non-empty)

  public static void pass_baton(process p)

pass_baton() to support coroutines @param p process to be resumed

  public static void pass_baton(process p,
                                boolean die)

pass baton to next process @param p process to be resumed @param die caller dies if true
