Method Detail

enforce

public void enforce(org.deidentifier.arx.framework.check.groupify.HashGroupifyDistribution distribution,
                    int numMaxSuppressedOutliers)

Description copied from class: SampleBasedCriterion

This method enforces the criterion on the current hash table. Criteria can be enforced by suppressing classes in the distribution by passing a PrivacyCondition. Criteria may abort early, if the threshold is reached (distribution.getNumOfSuppressedTuples() > numMaxSuppressedOutliers).

Specified by:

enforce in class SampleBasedCriterion

getRequirements

public int getRequirements()

Description copied from class: PrivacyCriterion

Returns the criterion's requirements.

Specified by:

getRequirements in class PrivacyCriterion

Returns:

getRiskThreshold

public double getRiskThreshold()

Returns the risk threshold

Returns:
