Constructor Detail

IPv4AddressAttribute

public IPv4AddressAttribute(InetAddress address)

Creates the new IPv4AddressAttribute with just the required address component.

Parameters:

address - a non-null InetAddress

IPv4AddressAttribute

public IPv4AddressAttribute(InetAddress address,
                            InetAddress mask)

Creates the new IPv4AddressAttribute with the optional address mask.

Parameters:

address - a non-null InetAddress

mask - an InetAddress or null if there is no mask

IPv4AddressAttribute

public IPv4AddressAttribute(InetAddress address,
                            PortRange range)

Creates the new IPv4AddressAttribute with the optional port range.

Parameters:

address - a non-null InetAddress

portRange - a non-null PortRange

IPv4AddressAttribute

public IPv4AddressAttribute(InetAddress address,
                            InetAddress mask,
                            PortRange range)

Creates the new IPv4AddressAttribute 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

getV4Instance

protected static IPAddressAttribute getV4Instance(String value)
                                           throws UnknownHostException

Returns a new IPv4AddressAttribute that represents the name indicated by the String provided. This is a protected method because you should never call it directly. Instead, you should call getInstance on IPAddressAttribute which provides versions that take both a String and a Node and will determine the protocol version correctly.

Parameters:

value - a string representing the address

Returns:

a new IPAddressAttribute

Throws:

UnknownHostException - if the address components is invalid

ParsingException - if any of the address components is invalid

encode

public String encode()

Description copied from class: AttributeValue

Encodes the value in a form suitable for including in XML data like a request or an obligation. This must return a value that could in turn be used by the factory to create a new instance with the same value.

Specified by:

encode in class AttributeValue

Returns:

a String form of the value
