Examples of com.sun.jmx.snmp.SnmpPduPacket

com.sun.jmx.snmp.SnmpPduPacket
Is the fully decoded representation of an SNMP packet.
You will not usually need to use this class, except if you decide to implement your own {@link com.sun.jmx.snmp.SnmpPduFactory SnmpPduFactory} object.
Classes are derived from SnmpPduPacket to represent the different forms of SNMP packets ( {@link com.sun.jmx.snmp.SnmpPduRequest SnmpPduRequest}, {@link com.sun.jmx.snmp.SnmpPduTrap SnmpPduTrap}, {@link com.sun.jmx.snmp.SnmpPduBulk SnmpPduBulk}).
The SnmpPduPacket class defines the attributes common to every form of SNMP packets.
This API is a Sun Microsystems internal API and is subject to change without notice.
