Example 1 with SnmpValue

use of com.sun.jmx.snmp.SnmpValue in project jdk8u_jdk by JetBrains.

the class SnmpMibTable method endRowAction.

/**
     * This method takes care of final RowStatus handling during the
     * set() phase of a SET request.
     *
     * In particular it will:
     *     <ul><li>either call <code>setRowStatus(<i>active</i>)</code>
     *         (<code> rowAction = <i>createAndGo</i> or <i>active</i>
     *         </code>),</li>
     *     <li>or call <code>setRowStatus(<i>notInService</i> or <i>
     *         notReady</i>)</code> depending on the result of <code>
     *         isRowReady()</code> (<code>rowAction = <i>createAndWait</i>
     *         </code>),</li>
     *     <li>or call <code>setRowStatus(<i>notInService</i>)</code>
     *         (<code> rowAction = <i>notInService</i></code>),
     *     <li>or call <code>removeTableRow()</code> (<code>
     *         rowAction = <i>destroy</i></code>),</li>
     *     <li>or generate a SnmpStatusException if the passed <code>
     *         rowAction</code> is not correct. This should be avoided
     *         since it would break SET request atomicity</li>
     *     </ul>
     * <p>
     * In principle, you should not need to redefine this method.
     * <p>
     * <code>endRowAction()</code> is called during the set() phase
     * of a SET request, after the actual set() on the varbind list
     * has been performed. The varbind containing the control variable
     * is updated with the value returned by setRowStatus() (if it is
     * not <code>null</code>).
     *
     * <p>
     * @param req    The sub-request that must be handled by this node.
     *
     * @param rowOid The <CODE>SnmpOid</CODE> identifying the table
     *               row involved in the operation.
     *
     * @param depth  The depth reached in the OID tree.
     *
     * @param rowAction The requested action as returned by <code>
     *        getRowAction()</code>: one of the RowStatus codes defined in
     *        {@link com.sun.jmx.snmp.EnumRowStatus}. These codes
     *        correspond to RowStatus codes as defined in RFC 2579,
     *        plus the <i>unspecified</i> value which is SNMP Runtime specific.
     *
     * @exception SnmpStatusException if the specified <code>rowAction</code>
     *            is not valid.
     *
     * @see com.sun.jmx.snmp.EnumRowStatus
