Method Detail

newPacket

public static TcpPacket 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 -

offset -

length -

Returns:

a new TcpPacket object.

Throws:

IllegalRawDataException

getHeader

public TcpPacket.TcpHeader 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 exist

hasValidChecksum

public boolean hasValidChecksum(InetAddress srcAddr,
                       InetAddress dstAddr,
                       boolean acceptZero)

checksum varification is necessary for IPv6(i.e. acceptZero must be false)

Parameters:

srcAddr -

dstAddr -

acceptZero -

Returns:

true if the packet represented by this object has a valid checksum; false otherwise.

getBuilder

public TcpPacket.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
