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

Graph.getStatisticsHandler介绍

[英]Answer this Graph's statistics handler, or null if there isn't one. Every call to this method on a particular graph delivers the same (==) answer.
[中]回答此图的统计处理程序，如果没有，则回答null。在特定图形上对该方法的每次调用都会提供相同的（=）答案。
