Class IPAddressAttribute

java.lang.Object

org.jboss.security.xacml.sunxacml.attr.AttributeValue

org.jboss.security.xacml.sunxacml.attr.IPAddressAttribute

All Implemented Interfaces:

Evaluatable, Expression

Direct Known Subclasses:

IPv4AddressAttribute, IPv6AddressAttribute

public abstract class IPAddressAttribute
extends AttributeValue

Represents the IPAddress datatype introduced in XACML 2.0. All objects of this class are immutable and all methods of the class are thread-safe.

To create an instance of an ipAddress from an encoded String or a DOM Node you should use the getInstance methods provided by this class. To construct an ipAddress instance directly, you must use the constructors provided by IPv4AddressAttribute and IPv6AddressAttribute. These will both create an attribute of XACML type ipAddress, but will handle the differences in these two representations correctly.

Since:

2.0

Constructor Detail

IPAddressAttribute

protected IPAddressAttribute(InetAddress address,
                  InetAddress mask,
                  PortRange range)

Creates the new IPAddressAttribute with all the optional components.

Parameters:

address - a non-null InetAddress

mask - an InetAddress or null if there is no mask

portRange - a non-null PortRange

Method Detail

getInstance

public static IPAddressAttribute getInstance(Node root)
                                      throws ParsingException

Returns a new IPAddressAttribute that represents the name at a particular DOM node.

Parameters:

root - the Node that contains the desired value

Returns:

a new IPAddressAttribute representing the appropriate value (null if there is a parsing error)

Throws:

ParsingException - if any of the address components is invalid

getInstance

public static IPAddressAttribute getInstance(String value)
                                      throws ParsingException

Returns a new IPAddressAttribute that represents the name indicated by the String provided.

Parameters:

value - a string representing the address

Returns:

a new IPAddressAttribute

Throws:

ParsingException - if any of the address components is invalid

getAddress

public InetAddress getAddress()

Returns the address represented by this object.

Returns:

the address

getMask

public InetAddress getMask()

Returns the mask represented by this object, or null if there is no mask.

Returns:

the mask or null

getRange

public PortRange getRange()

Returns the port range represented by this object which will be unbound if no range was specified.

Returns:

the range

equals

public boolean equals(Object o)

Returns true if the input is an instance of this class and if its value equals the value contained in this class.

Overrides:

equals in class Object

Parameters:

o - the object to compare

Returns:

true if this object and the input represent the same value

hashCode

public int hashCode()

Returns the hashcode value used to index and compare this object with others of the same type.

Overrides:

hashCode in class Object

Returns:

the object's hashcode value

toString

public String toString()

Converts to a String representation.

Overrides:

toString in class Object

Returns:

the String representation
