/**
 * Defines the interface of the object in charge of encoding and decoding SNMP packets.
 * <P>
 * You will not usually need to use this interface, except if you
 * decide to replace the default implementation <CODE>SnmpPduFactoryBER</CODE>.
 * <P>
 * An <CODE>SnmpPduFactory</CODE> object is attached to an
 * {@link com.sun.jmx.snmp.daemon.SnmpAdaptorServer SNMP protocol adaptor}
 * or an {@link com.sun.jmx.snmp.SnmpPeer SnmpPeer}.
 * It is used each time an SNMP packet needs to be encoded or decoded.
 * <BR>{@link com.sun.jmx.snmp.SnmpPduFactoryBER SnmpPduFactoryBER} is the default
 * implementation.
 * It simply applies the standard ASN.1 encoding and decoding
 * on the bytes of the SNMP packet.
 * <P>
 * It's possible to implement your own <CODE>SnmpPduFactory</CODE>
 * object and to add authentication and/or encryption to the
 * default encoding/decoding process.
