Method Details

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.

toPortNumbers

private List<Integer> toPortNumbers(byte[] bitMap)

getAddress

public Inet4Address getAddress()

Returns:

address

getProtocol

public IpNumber getProtocol()

Returns:

protocol

getBitMap

public byte[] getBitMap()

Returns:

bitMap. Another view of portNumbers.
