All Implemented Interfaces:

CsvRecordOutputWriter, Activity, ReplaceableActivity, Serializable

public class Ipv4Activity
extends IpActivity

Encapsulates all available/decoded IPv4 packet fields and provides a compatible JNetPcap Ip4 object. Instances of this class are excluded from output by default in order to decrease verbosity, AbstractActivity.setExcludedFromOutput(boolean) may be called to change this behaviour.

Constructor Detail

Ipv4Activity

public Ipv4Activity(PcapActivity source,
                    org.krakenapps.pcap.decoder.ip.Ipv4Packet ipv4Packet)

Constructs a new IPv4 activity that will not be included in the final output. The source pcap activity will be replaced and the packet fields encapsulated.

Parameters:

source - the Pcap activity from which this packet was decoded (final one, if fragmented).

ipv4Packet - the decoded IPv4 packet (Kraken)

Method Detail

getExplicitCongestionNotification

public int getExplicitCongestionNotification()

Throws:

IllegalStateException - since it is not yet implemented

getInternetHeaderLength

public int getInternetHeaderLength()

Returns:

the length of the IPv4 packet header in bytes

getDifferentiatedServicesCodePoint

public int getDifferentiatedServicesCodePoint()

Returns:

the differentiated services code point value

getTotalLength

public int getTotalLength()

Returns:

the total packet size in bytes

getIdentification

public int getIdentification()

Returns:

the identification value

getFlags

public int getFlags()

Returns:

the flags combined in one integer

getFragmentOffset

public int getFragmentOffset()

Returns:

the fragment offset value

getTimeToLive

public int getTimeToLive()

Returns:

the TTL value

getHeaderChecksum

public int getHeaderChecksum()

Returns:

the checksum

getOptions

public byte[] getOptions()

Returns:

the options as encountered

getIpv4

public org.jnetpcap.protocol.network.Ip4 getIpv4()

Returns:

the JNetPcap representation of the IPv4 packet iff available, null otherwise (e.g. if the packet is fragmented)

toString

public String toString()

Overrides:

toString in class IpActivity
