本文整理了Java中org.eclipse.rdf4j.query.Dataset类的一些代码示例，展示了Dataset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。Dataset类的具体详情如下：
包路径：org.eclipse.rdf4j.query.Dataset
类名称：Dataset

Dataset介绍

[英]Represents a dataset against which operations can be evaluated. A dataset consists of a default graph for read and using operations, which is the RDF merge of one or more graphs, a set of named graphs, and a single update graph for INSERT and DELETE. See SPARQL Query Language for RDF for more info.
[中]表示可以对其计算操作的数据集。数据集由一个用于读取和使用操作的默认图组成，该图是一个或多个图的RDF merge，一组命名图，以及一个用于插入和删除的更新图。有关更多信息，请参见SPARQL Query Language for RDF。
