Packet (nl.sidnlabs:pcap-lib 0.1.3 API)

java.lang.Object
- nl.sidnlabs.pcap.packet.Packet

Direct Known Subclasses:

DNSPacket, ICMPPacket
```
public class Packet
extends Object
```
Packet contains a combination of IP layer and UDP/TCP/DNS layer data Fragmented IP is joined into a single Packet object Fragmented UDP is joined into a single Packet object TCP session with multiple DNS queries in a stream before the PSH or FIN will cause multiple DNS messages to get added to the Packet object.
