                              int offset,
                              int length,
                              TcpOptionKind number)

Specified by:

newInstance in interface PacketFactory<TcpPacket.TcpOption,TcpOptionKind>

Parameters:

rawData - rawData

offset - offset

length - length

number - number

Returns:

a new data object.

newInstance

public TcpPacket.TcpOption newInstance(byte[] rawData,
                              int offset,
                              int length)

Specified by:

newInstance in interface PacketFactory<TcpPacket.TcpOption,TcpOptionKind>

Parameters:

rawData - rawData

offset - offset

length - length

Returns:
