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

Dataset.getDefaultGraphs介绍

[英]Gets the default graph URIs of this dataset. An empty default graph set and a non-empty named graph set indicates that the default graph is an empty graph. However, if both the default graph set and the named graph set are empty, that indicates that the store's default behaviour should be used.
[中]获取此数据集的默认图形URI。空的默认图集和非空的命名图集表示默认图是空图。但是，如果默认图形集和命名图形集都为空，则表示应使用存储的默认行为。
