本文整理了Java中org.apache.commons.rdf.api.Dataset.size()方法的一些代码示例，展示了Dataset.size()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.size()方法的具体详情如下：
包路径：org.apache.commons.rdf.api.Dataset
类名称：Dataset
方法名：size

Dataset.size介绍

[英]Number of quads contained by the dataset.

The count of a set does not include duplicates, consistent with the Quad#equals(Object) equals method for each Quad.
[中]数据集包含的四边形数。
集合的计数不包括重复项，这与每个四元组的Quad#equals（Object）equals方法一致。
