Method Detail

newPacket

public static LlcPacket newPacket(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 LlcPacket object.

Throws:

IllegalRawDataException - if parsing the raw data fails.

getHeader

public LlcPacket.LlcHeader getHeader()

Description copied from class: AbstractPacket

Returns the Header object representing this packet's header. This subclass have to override this method if the packet represented by the subclass has a header.

Specified by:

getHeader in interface Packet

Overrides:

getHeader in class AbstractPacket

Returns:

the Header object representing this packet's header. May be null if the header doesn't exist

getPayload

public Packet getPayload()

Description copied from class: AbstractPacket

Returns the Packet object representing this packet's payload. This subclass have to override this method if the packet represented by the subclass has a payload.

Specified by:

getPayload in interface Packet

Overrides:

getPayload in class AbstractPacket

Returns:

the Packet object representing this packet's payload. May be null if the payload doesn't exist

getBuilder

public LlcPacket.Builder getBuilder()

Description copied from interface: Packet

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

Specified by:

getBuilder in interface Packet

Specified by:

getBuilder in class AbstractPacket

Returns:

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