Class AttValueCount

java.lang.Object
  anatomy.AttValueCount

All Implemented Interfaces:

java.lang.Comparable

public class AttValueCount
extends java.lang.Object
implements java.lang.Comparable

This class manages the counts of sensitive attribute values. Associated with each object is a double attribute value and the count of tuples in the dataset that have that value.

Field Summary

private int	count Number of associated tuples
private double	value Attribute value

Constructor Summary

AttValueCount(double value, int count)
Class constructor

Method Summary

int	compareTo(java.lang.Object o) Used for sorting AttValueCounts in DESCENDING order
boolean	decrement() Decrement the count for this attribute value
int	getCount() Getter for the tuple count
double	getValue() Getter for the attribute value
java.lang.String	toString()
