本文整理了Java中fr.inria.corese.kgram.core.Query类的一些代码示例，展示了Query类的具体用法。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。Query类的具体详情如下：
包路径：fr.inria.corese.kgram.core.Query
类名称：Query

Query介绍

[英]KGRAM Query also used for subquery
[中]KGRAM查询也用于子查询

代码示例

  1. Query complete(Query q1, Query q2) {
  2.   q1.setOuterQuery(this);
  3.   q2.setOuterQuery(this);
  4.   setGlobalQuery(getBody());
  5.   setSelect(q1, q2);
  6.   collect();
  7.   setAST(q2.getAST());
  8.   return this;
  9. }
