Method Detail

initializeUserData

public abstract void initializeUserData(SimUser user)

Method, called at the start of the simulation, for every simulated user, to initialize all the components and variables from SimUser, that the reputation model will be using.

This method is called for all users involved in a scenario, when the simulation starts.

Parameters:

user - the SimUser to be initialized.

recalculateReputation

public abstract void recalculateReputation(SimUser user,
                                           float[] rating)

Method, called with every rating, to re-estimate the values from SimUser, that the reputation model will be using.

This method is called for every SimpleDirectionalRate operation in a scenario to apply the rating.

Parameters:

user - the SimUser receiving the rating.

rating - the ActionSequence record for the rating.

updateReputationSeries

public abstract void updateReputationSeries(SimUser user,
                                            float[] rating,
                                            SimulatorPanel simulatorPanel)

Method, called with every rating, to update all Series from SimUser, that the reputation model will be using and call the ChartController to update the UI charts.

This method is called for every SimpleDirectionalRate operation in a scenario to update the charts with the latest reputation values after recalculateReputation(SimUser, float[]) is invoked.

Parameters:

user - the SimUser receiving the rating.

rating - the ActionSequence record for the rating.

simulatorPanel - the UI's SimulatorPanel that is needed in order to access and update the charts.

addChartSeries

public abstract void addChartSeries(SimulatorModel simulatorModel,
                                    SimulatorPanel simulatorPanel)

Method, called at the start of the simulation, to add or clear all the series within the Chart Datasets (XYSeriesCollection), that are used from the reputation model.

Parameters:

simulatorModel - the SimulatorModel containing the chart dataSets to be added.

simulatorPanel - the UI's SimulatorPanel that is needed in order to access the charts.

getMainSeriesKey

public java.lang.String getMainSeriesKey()

setMainSeriesKey

public void setMainSeriesKey(java.lang.String mainSeriesKey)

updateSeriesBykey

public void updateSeriesBykey(java.lang.String key,
                              SimUser user,
                              SimulatorPanel simulatorPanel)

Method, called with every rating, to update a specific Series from SimUser, that the reputation model will be using and call the ChartController to update the UI chart.

Parameters:

key - the key name of the dataset stored in the XYSeriesCollection

user - the SimUser receiving the rating.

simulatorPanel - the UI's SimulatorPanel that is needed in order to access the charts.

getDataSetByKey

public org.jfree.data.xy.XYSeriesCollection getDataSetByKey(java.lang.String key)

Method to retrieve the XYSeriesCollection by key name.

Parameters:

key - key name of the dataset stored in the XYSeriesCollection

Returns:

the XYSeriesCollection that contains the Series with name = key.

getChartByKey

public org.jfree.chart.JFreeChart getChartByKey(SimulatorPanel simulatorPanel,
                                                java.lang.String key)

Method to retrieve the JFreeChart containing the chart series with name "key".

Parameters:

simulatorPanel - the UI's SimulatorPanel that is needed in order to access the charts.

key - key name of the dataset stored in the XYSeriesCollection

Returns:

the JFreeChart that contains the Series with name = key.
