本文整理了Java中xdi2.core.Graph.clear()
方法的一些代码示例,展示了Graph.clear()
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.clear()
方法的具体详情如下:
包路径:xdi2.core.Graph
类名称:Graph
方法名:clear
[英]Clears all data from the graph. This is equivalent to calling getRootContextNode().clear();
[中]清除图形中的所有数据。这相当于调用getRootContextNode()。清除();

this.lastSuccessfulReader = xdiReader;

} catch(Exception ex) {
