本文整理了Java中net.ontopia.topicmaps.query.core.QueryResultIF.next方法的一些代码示例，展示了QueryResultIF.next的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。QueryResultIF.next方法的具体详情如下：
包路径：net.ontopia.topicmaps.query.core.QueryResultIF
类名称：QueryResultIF
方法名：next

QueryResultIF.next介绍

[英]PUBLIC: Steps to the next match, returning true if a valid match was found, and false if there are no more matches. Must be called before values can be returned.
[中]PUBLIC：转到下一个匹配项，如果找到有效匹配项，则返回true，如果没有其他匹配项，则返回false。必须在返回值之前调用。
