示例1: getNext
import sun.management.snmp.util.SnmpCachedData; //导入方法依赖的package包/类
/**
* Returns the index that immediately follows the given
* <var>index</var>. The returned index is strictly greater
* than the given <var>index</var>, and is contained in the table.
* <br>If the given <var>index</var> is null, returns the first
* index in the table.
* <br>If there are no index after the given <var>index</var>,
* returns null.
* This method is an optimization for the case where the
* SnmpTableHandler is in fact an instance of SnmpCachedData.
