Constructor Detail

OSS

public OSS(java.lang.String ficheroScript)

Constructor of the class. It configures the execution of the algorithm by reading the configuration script that indicates the parameters that are going to be used.

Parameters:

ficheroScript - Name of the configuration script that indicates the parameters that are going to be used during the execution of the algorithm

Method Detail

run

public void run()

The main method of the class that includes the operations of the algorithm. It includes all the operations that the algorithm has and finishes when it writes the output information into files.

leerConfiguracion

public void leerConfiguracion(java.lang.String ficheroScript)

Obtains the parameters used in the execution of the algorithm and stores them in the private variables of the class

Overrides:

leerConfiguracion in class Metodo

Parameters:

ficheroScript - Name of the configuration script that indicates the parameters that are going to be used during the execution of the algorithm

normalizar

protected void normalizar()
                   throws CheckException

This function builds the data matrix for reference data and normalizes inputs values

Overrides:

normalizar in class Metodo

Throws:

CheckException - Can not be normalized
