Method Detail

getAnonymitySet

public IdentityStoreBlock[] getAnonymitySet()

setAnonymitySet

public void setAnonymitySet(IdentityStoreBlock[] anonymitySet)

Sets the list of identities to be used for the anonymity set.

Parameters:

anonymitySet - a list of identities to be used

getAnonymity

public IdentityStoreBlock getAnonymity(int i)

getSource

public IdentityStoreBlock getSource()

setSource

public void setSource(IdentityStoreBlock source)

Sets the source identity of this graph.

Parameters:

source - the source identity to be set

Throws:

IllegalArgumentException - if the source is not part of the anonymity set

NullPointerException - if the source is null

getTarget

public IdentityStoreBlock getTarget()

setTarget

public void setTarget(IdentityStoreBlock target)

Sets the target identity of this graph.

Parameters:

target - the target identity to be set

Throws:

IllegalArgumentException - if the target is not part of the anonymity set

NullPointerException - if the target is null

getAnonymitySetSize

public int getAnonymitySetSize()

getAnonymityIndex

public int getAnonymityIndex(IdentityStoreBlock isb)

add

public boolean add(Edge g)

contains

public boolean contains(Edge g)

Check for a edge covering the mentioned points.

Parameters:

g - the edge to be searched for

Returns:

true if the graph has been found at least once

addAll

public boolean addAll(Collection<? extends Edge> g)

getAnonIdentity

public IdentityStoreBlock getAnonIdentity(int i)

Get an identity from the specified anonymity set.

Parameters:

i - the index of the identity to obtain

Returns:

the identity store block specified

Throws:

ArrayIndexOutOfBoundsException - if i is outside the bounds of the anonymity set

allTargetsReached

public boolean allTargetsReached()

check if all members of the anonymity set hve been reached at least once.

Returns:

true if all members have been reached

targetReached

public boolean targetReached(IdentityStoreBlock is)

Checks if a specific identity store block is already reached by this graph.

Parameters:

is - the identity store block

Returns:

true if the identity store block has been reached already in the past

Throws:

NullPointerException - if the specified identity stor block is null
