Constructor Detail

Policy

public Policy(int lastAttributeValue,
              int maxAttributeCreations,
              HashMap<String,PolicyAxis> axes,
              HashMap<PolicyAttributeUid,TreeSet<Integer>> attributeToInt)

Policy

public Policy(int maxAttributeCreations)

Instantiate an empty policy allowing the given max number of revocations of attributes

Parameters:

maxAttributeCreations - the maximum number of possible attributes

Method Detail

addAxis

public Policy addAxis(String name,
                      String[] attributes,
                      boolean hierarchical)
               throws CosmianException

Add the given Axis to this policy and return the policy

Parameters:

name - axis name

attributes - policy attributes of the axis

hierarchical - whether the axis is hierarchical

Returns:

the update Policy

Throws:

CosmianException - if the addition fails

toVendorAttribute

public VendorAttribute toVendorAttribute(String abeImplementation)
                                  throws CosmianException

Convert the policy to a KMIP Vendor attribute that can be set on a KMIP Object

Parameters:

abeImplementation - abe_gpsw or cover_crypt

Returns:

the VendorAttribute

Throws:

CosmianException - if the JSON cannot be serialized

fromVendorAttributes

public static Policy fromVendorAttributes(Attributes attributes,
                                          String abeImplementation)
                                   throws CosmianException

Throws:

CosmianException

getLastAttributeValue

public int getLastAttributeValue()

The last attribute value that was assigned. This value is usually incremented as attributes are revoked. The value should therefore no exceed the value returned by getMaxAttributeCreations()

Returns:

the last attribute value

getMaxAttributeCreations

public int getMaxAttributeCreations()

getAxes

public HashMap<String,PolicyAxis> getAxes()

getAttributeToInt

public HashMap<PolicyAttributeUid,TreeSet<Integer>> getAttributeToInt()

lastAttribute

public Policy lastAttribute(int lastAttribute)

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
