Class LatticeManager

java.lang.Object
  incognito.LatticeManager

public class LatticeManager
extends java.lang.Object

Constructed from a super root and the depth of quasi-identifier attributes, this class manages the generalization lattice entries.

Field Summary

private int[]	dghDepths Depths of qi-attributes
private LatticeEntry	lastReturned Value of the last entry that was returned
private int	nextEntryIndex Index of the next root to be visited
private LatticeEntry[]	roots List of currently unvisited roots
private java.util.LinkedList<LatticeEntry>	successfulEntries List of successfully anonymized lattice entries

Constructor Summary

LatticeManager(LatticeEntry superRoot, int[] dghDepths)
Class constructor

Method Summary

java.util.LinkedList<LatticeEntry>	getSuccessfulEntries() Getter for successful entries
boolean	hasNext() Checks if there are more lattice entries that need visiting
LatticeEntry	next() Get the next entry from the generalization lattice
void	setResult(boolean successFlag, AnonRecordTable anonTable, EquivalenceTable eqTable) Set the anonymization result for the last lattice entry.

Constructor Detail

LatticeManager

public LatticeManager(LatticeEntry superRoot,
                      int[] dghDepths)

Class constructor

Parameters:

superRoot - Lattice entry whose children will be visited

dghDepths - Maximum depth of domain generalization hierarchies of the qi-attributes

Method Detail

hasNext

public boolean hasNext()

Checks if there are more lattice entries that need visiting

Returns:

true if there are more, false otherwise

getSuccessfulEntries

public java.util.LinkedList<LatticeEntry> getSuccessfulEntries()

Getter for successful entries

Returns:

list of lattice entries that map to k-anonymous views

next

public LatticeEntry next()

Get the next entry from the generalization lattice

Returns:

The next unvisited lattice entry

setResult

public void setResult(boolean successFlag,
                      AnonRecordTable anonTable,
                      EquivalenceTable eqTable)

Set the anonymization result for the last lattice entry.

Parameters:

successFlag - true if the last returned entry satisfied the privacy/anonymity requirement, false otherwise
