本文整理了Java中org.openrdf.query.Update类的一些代码示例，展示了Update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。Update类的具体详情如下：
包路径：org.openrdf.query.Update
类名称：Update

Update介绍

[英]An update operation on a repository that can be formulated in one of the supported query languages (for example SPARQL).
[中]存储库上的更新操作，可以用一种受支持的查询语言（例如SPARQL）表示。
