Method Detail

getIcmpType

public byte getIcmpType()

Returns:

the icmpType

setIcmpType

public ICMP setIcmpType(byte icmpType)

Parameters:

icmpType - to set

getIcmpCode

public byte getIcmpCode()

Returns:

the icmp code

setIcmpCode

public ICMP setIcmpCode(byte icmpCode)

Parameters:

icmpCode - code to set

getChecksum

Overrides:

equals in class BasePacket

deserialize

public IPacket deserialize(byte[] data,
                  int offset,
                  int length)

Description copied from interface: IPacket

Deserializes this packet layer and all possible payloads.

offset - offset to start deserializing from

length - length of the data to deserialize

Returns:

the deserialized data
