 where:

 ADDRESS         An 32 bit Internet address

 PROTOCOL        An 8 bit IP protocol number

 <BIT MAP>       A variable length bit map.  The bit map must be a
                 multiple of 8 bits long.

Method Detail

newInstance

public static DnsRDataWks newInstance(byte[] rawData,
                                      int offset,
                                      int length)
                               throws IllegalRawDataException

A static factory method. This method validates the arguments by ByteArrays.validateBounds(byte[], int, int), which may throw exceptions undocumented here.

Parameters:

rawData - rawData

offset - offset

length - length

Returns:

a new DnsRDataWks object.

Throws:

IllegalRawDataException - if parsing the raw data fails.

getAddress

public java.net.Inet4Address getAddress()

Returns:

address

getProtocol

public IpNumber getProtocol()

Returns:

protocol

getBitMap

public byte[] getBitMap()

Returns:

bitMap. Another view of portNumbers.
