本文整理了Java中org.apache.jena.query.Query.setResultVars方法的一些代码示例，展示了Query.setResultVars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.setResultVars方法的具体详情如下：
包路径：org.apache.jena.query.Query
类名称：Query
方法名：setResultVars

Query.setResultVars介绍

[英]Fix up when the query has "" (when SELECT * or DESCRIBE ) and for a construct query. This operation is idempotent.
[中]当查询包含“”（当选择或描述*时）和构造查询时进行修复。这个运算是幂等的。
