public abstract class ByteOption
extends DhcpOption

The Dynamic Host Configuration Protocol (DHCP) provides a framework for passing configuration information to hosts on a TCP/IP network. Configuration parameters and other control information are carried in tagged data items that are stored in the 'options' field of the DHCP message. The data items themselves are also called "options." This abstract base class is for options that carry an unsigned short value (16 bit).

private short byteValue

The byte value (represented as a short because of the unsignedness).

ByteOption

public ByteOption()

Method Detail

setData

public void setData(byte[] data)

Description copied from class: DhcpOption

Set the data (wire format) from a byte array. The default implementation just records the data as a byte array. Subclasses may parse the data into something more meaningful.

Overrides:

setData in class DhcpOption

getData

public byte[] getData()

Description copied from class: DhcpOption

Get the data (wire format) into a byte array. Subclasses must provide an implementation which serializes the parsed data back into a byte array if they override DhcpOption.setData(byte[]).

Overrides:

getData in class DhcpOption

Returns:

byte[]

getByteValue

public short getByteValue()

setShortValue

public void setShortValue(short shortValue)
