PREFERENCE      A 16 bit integer which specifies the preference given to
                this RR among others at the same owner.  Lower values
                are preferred.

EXCHANGE        A <domain-name> which specifies a host willing to act as
                a mail exchange for the owner name.

Method Details

newInstance

public static DnsRDataMx 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 DnsRDataMx object.

Throws:

IllegalRawDataException - if parsing the raw data fails.

getPreference

Returns:

preference

getPreferenceAsInt

public int getPreferenceAsInt()

Returns:

preference

getExchange

public DnsDomainName getExchange()

Returns:

exchange

length

public int length()

Specified by:

length in interface DnsResourceRecord.DnsRData

Returns:

length

getRawData

public byte[] getRawData()

Specified by:

getRawData in interface DnsResourceRecord.DnsRData

toString

public String toString(String indent)

Specified by:

toString in interface DnsResourceRecord.DnsRData

Parameters:
