Constructor Detail

VAList

public VAList()

Creates a new instance of VAList

Method Detail

addValueNClass

public void addValueNClass(double value,
                           double _class)

Adds an attribute value with its associated class to this list. If no frequency list for this value exists yet, then creates one new.

Parameters:

value - The value of the attribute

_class - The class of the instance from which the value has been extracted

getVA

public valueAssociations getVA(double ref)

this method returns a object with the frequencies list associated to the value passed as parameter

Parameters:

ref - The class of the list we want to retrieve

Returns:

The object with the frequencies list of this class

getnVA

public valueAssociations getnVA(int i)

This method returns the valueAssociations object which is in position 'i'. It is intended for sequential access.

Parameters:

i - The index of the VA object we want

Returns:

The element VA at position 'i'

getNumVA

public int getNumVA()

This method gives the number of VA elements stored (i.e. the number of different values)

Returns:

The number of elements in the list

getNumElems

public int getNumElems()

This method returns the total of elements ever added to this list.

Returns:

The total number of pairs value-class ever added
