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

public short getChecksum()

Returns:

the checksum

setChecksum

public ICMP setChecksum(short checksum)

Parameters:

checksum - the checksum to set

serialize

public byte[] serialize()

Serializes the packet. Will compute and set the following fields if they are set to specific values at the time serialize is called: -checksum : 0 -length : 0

Returns:

a byte[] containing this packet and payloads

hashCode

public int hashCode()

Overrides:

hashCode in class BasePacket

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class BasePacket

deserialize

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

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

Throws:

PacketParsingException
