Class MeasurementEvolution

java.lang.Object

simulation.MeasurementEvolution

Direct Known Subclasses:

MeasurementEvolutionSociogram

public abstract class MeasurementEvolution
extends java.lang.Object

This class records the evolution of several metrics for each iteration. Then, the recorded values can be printed in a PrintStream. This class is abstract and needs that the method recordValues is implemented in the subclasses. This method must record the values that are specific of a particular simulator. The subclases also must set the names of the metrics in the metrics attribute

Field Detail

metrics

protected java.lang.String[] metrics

Names of the metrics. The subclasses must set thes value

numIterations

private int numIterations

Number of iterations

values

protected double[][] values

Measurement values of the metrics for each iteration, in which values[iteration][metric] represents for a particular iteration the measurement value of the corresponding metric number.

METRIC_FORMAT

private static java.text.DecimalFormat METRIC_FORMAT

Format of the double values printed in the text file for representing the sociogrametric values.

COLUMN_LENGTH

public static int COLUMN_LENGTH

Number of characters that is used for representing each column

Constructor Detail

MeasurementEvolution

public MeasurementEvolution(int numIterations,
                    int numMetrics)

Constructor of the class. It also needs the number of iterations.

Parameters:

numIterations - Number of iterations and the number of metrics.

Method Detail

recordValues

public abstract void recordValues()

The implementation must record the measurment values specific of each simulator. For this reason, this method is abstract and must be implemented in the subclasses. It can call the other method recordValues(iteration, valuesIter).

recordValues

public void recordValues(int iteration,
                double[] valuesIter)

Records the measurement values of a particular iteration

Parameters:

iteration - The number of the iteration in which the measurement values are recorded.

valuesIter - The measurement values of a particular iteration following the same order of metrics as the given in the constructor.

saveValues

public void saveValues(java.io.PrintStream out)

Save the all the recorded measurement values by printing these in an open PrintStream

Parameters:

out - The stream where the measurement values are printed.
