Class RandomNumberGeneratorCallObserver

java.lang.Object

fern.simulation.observer.Observer

fern.simulation.observer.RandomNumberGeneratorCallObserver

All Implemented Interfaces:

GnuPlotObserver

public class RandomNumberGeneratorCallObserver
extends Observer
implements GnuPlotObserver

Observes the calls to the random number generator and count the number of drawn random number of different distributions. These calls are crucial for the stochastic algorithms because besides algebraic calculations are these the most time consuming operations.

This observer does take repeats into account. If you repeat the simulation, you will get an average over the results each run.

Constructor Detail

RandomNumberGeneratorCallObserver

public RandomNumberGeneratorCallObserver(Simulator sim)

Creates the observer for the given simulator.

Parameters:

sim - simulator

Method Detail

activateReaction

public void activateReaction(int mu,
                             double tau,
                             Simulator.FireType fireType,
                             int times)

Do nothing.

Specified by:

activateReaction in class Observer

Parameters:

mu - the reaction which is supposed to fire

tau - the time the reaction fires (at this time Simulator.getTime() does not necessarily yield the firing time)

fireType - the type of the firing

times - TODO

finished

public void finished()

Calculates the average.

Specified by:

finished in class Observer

started

public void started()

Resets the count variables of the random number generator calls.

Specified by:

started in class Observer

Stochastics.resetCounts()

step

public void step()

Do nothing.

Specified by:

step in class Observer

theta

public void theta(double theta)

Do nothing.

Specified by:

theta in class Observer

Parameters:

theta - moment in time

getStyles

public String[] getStyles()

Description copied from interface: GnuPlotObserver

Gets the styles for the columns. If you don't want styles, just return null!

Specified by:

getStyles in interface GnuPlotObserver

Returns:

styles for the columns

toGnuplot

public GnuPlot toGnuplot()

Description copied from interface: GnuPlotObserver

Creates a new GnuPlot object and passes the actual observer data to it.

Specified by:

toGnuplot in interface GnuPlotObserver

Returns:

the created GnuPlot object

toGnuplot

public GnuPlot toGnuplot(GnuPlot gnuplot)

Description copied from interface: GnuPlotObserver

Passes the actual observer data to a GnuPlot object.

Specified by:

toGnuplot in interface GnuPlotObserver

Parameters:

gnuplot - the GnuPlot object to pass the data to

Returns:

the GnuPlot object

toString

public String toString()

Overrides:

toString in class Object
