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

Graph.size介绍

[英]Number of triples contained by the graph.

The count of a set does not include duplicates, as determined by the equals method for each Triple.
[中]图形包含的三元组数。
集合的计数不包括重复项，由每个三元组的equals方法确定。
