Class SimTime

java.lang.Object
  TaxiProject05.environment.SimTime

All Implemented Interfaces:

java.io.Serializable

public class SimTime
extends java.lang.Object
implements java.io.Serializable

Holds the time in the simulation. Thread safe. Examples: //get current time double timemillis = SimTime.getInstance().getCurrentTimeMillis(); Date d = SimTime.getInstance().getCurrentDate(); //change speed of simulation SimTime.getInstance().setTimeFactor(SimTime.TimeFactor_Fast);

Method Detail

getInstance

public static SimTime getInstance()

Use this -> Get the singleton instance.

Returns:

The single instance of Environment class.

resetTime

public void resetTime()

Nollställer tiden till standard-starttiden.

setTime

public void setTime(long t)

Sets the simulation time to a specific datetime.

Parameters:

t - the time to set to in millis. Date.getTime().

getTimeFactor

public long getTimeFactor()

Returns:

Returns the timeFactor.

setTimeFactor

public void setTimeFactor(long timeFactor)

Change the factor for the time simulation. Set it to 1 leads to realtime Set it to 60 leads to 60 times faster, 1 min in the simulations takes 1 sek. Set it to 0 pauses. (Needs testing)

Parameters:

timeFactor - The timeFactor to set.

getCurrentTimeMillis

public long getCurrentTimeMillis()

Get the current time in the simulation. in

Returns:

milliseconds since 1970-01-01 00:00.

getCurrentDate

public java.util.Date getCurrentDate()

Gets the current Date in the simulation. (This includes the time as well)

Returns:

Date in the simulation.

getRealDate

public java.util.Date getRealDate(java.util.Date d)

Converts a simulation time to a real system time.

Parameters:

d - a simulation time.

Returns:

the real system time.

setAlarm

public void setAlarm(java.util.TimerTask task,
                     java.util.Date time)

Schedule a timer task to a specific time. Note: This doesn't work yet when changing the speed of the time!

Parameters:

task - A Task with the method that should be executed the specified time.

time - The time when the task should be done.
