<div class="section"><p>The <a href="javadoc/com/ibm/as400/util/commtrace/IPPacket.html">IPPacket class</a> is the abstract superclass
|
||
|
|
for creating classes that represent specific kinds of packets. The subclasses
|
||
|
|
of IPPacket include:</p>
|
||
|
|
<ul><li>ARPPacket</li>
|
||
|
|
<li>IP4Packet</li>
|
||
|
|
<li>IP6Packet</li>
|
||
|
|
<li>UnknownPacket</li>
|
||
|
|
</ul>
|
||
|
|
<p>Packet classes enable you to retrieve the type of packet and access
|
||
|
|
the raw data (the header and payload) that the packet contains. All the subclasses
|
||
|
|
use similar constructors and include one additional method that returns a
|
||
|
|
printable version of the packet contents as a String.</p>
|
||
|
|
<p>All the Packet
|
||
|
|
class constructors take a byte array of packet data as an argument, but the
|
||
|
|
ARPPacket also requires an integer that specifies the type of frame. Creating
|
||
|
|
an instance of a Packet class automatically creates the appropriate Header
|
||
|
|
object. </p>
|
||
|
|
<p>The Packet classes provide methods that allow you to perform
|
||
|
|
a variety of actions that include the following:</p>
|
||
|
|
<ul><li>Retrieve the name and type of the packet</li>
|
||
|
|
<li>Set the type of the packet</li>
|
||
|
|
<li>Return the top-level Header object associated with the packet</li>
|
||
|
|
<li>Return all the packet data as an unformatted String </li>
|
||
|
|
<li>Return specific data from the packet as a formatted String</li>
|
||
|
|
</ul>
|
||
