Method Detail

newInstance

public static DnsResourceRecord 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:

offset - offset

length - length

Returns:

a new DnsResourceRecord object.

Throws:

IllegalRawDataException - if parsing the raw data fails.

getBuilder

public DnsResourceRecord.Builder getBuilder()

Returns:

a new Builder object populated with this object's fields.

getRawData

public byte[] getRawData()

Returns:

the raw data.

length
