Method Detail

put

void put(DataRange dataRange,
         PrivacyConstraint.PrivacyLevel privacyLevel)

Set privacy level of the given data range.

Parameters:

dataRange - representing the range for which the privacy is set

privacyLevel - the level of privacy for the given data range

putRow

void putRow(int rowIndex,
            int rowLength,
            PrivacyConstraint.PrivacyLevel privacyLevel)

putCol

void putCol(int colIndex,
            int colLength,
            PrivacyConstraint.PrivacyLevel privacyLevel)

putElement

void putElement(int rowIndex,
                int colIndex,
                PrivacyConstraint.PrivacyLevel privacyLevel)

getPrivacyLevel

Map<DataRange,PrivacyConstraint.PrivacyLevel> getPrivacyLevel(DataRange searchRange)

Get the data ranges and related privacy levels within given data search range.

Parameters:

searchRange - the range from which all privacy levels are retrieved

Returns:

all mappings from range to privacy level within the given search range

getPrivacyLevelOfElement

Map<DataRange,PrivacyConstraint.PrivacyLevel> getPrivacyLevelOfElement(long[] searchIndex)

Get the data ranges and related privacy levels of the element with the given index.

Parameters:

searchIndex - index of element

Returns:

all mappings from range to privacy level for the given search element

getDataRangesOfPrivacyLevel

DataRange[] getDataRangesOfPrivacyLevel(PrivacyConstraint.PrivacyLevel privacyLevel)

Get all data ranges for the given privacy level.

Parameters:

privacyLevel - for which data ranges are found

Returns:

all data ranges with the given privacy level

removeAllConstraints

void removeAllConstraints()

Remove all fine-grained privacy constraints.

hasConstraints

boolean hasConstraints()

True if any fine-grained constraints has been set.

Returns:

true if any fine-grained constraint is set

getAllConstraints

Map<String,long[][][]> getAllConstraints()

Get all fine-grained constraints as a map from privacy level to an array of data ranges represented as two-dimensional long arrays.

Returns:

map from privacy level to array of data ranges

getAllConstraintsList

ArrayList<Map.Entry<DataRange,PrivacyConstraint.PrivacyLevel>> getAllConstraintsList()

Return all fine-grained privacy constraints as an arraylist.

Returns:

all constraints

getRowPrivacy
