本文整理了Java中org.janusgraph.core.JanusGraph.close()方法的一些代码示例,展示了JanusGraph.close()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。JanusGraph.close()方法的具体详情如下:
包路径:org.janusgraph.core.JanusGraph
类名称:JanusGraph
方法名:close

JanusGraph.close介绍

[英]Closes the graph database.

Closing the graph database causes a disconnect and possible closing of the underlying storage backend and a release of all occupied resources by this graph database. Closing a graph database requires that all open thread-independent transactions have been closed - otherwise they will be left abandoned.
[中]关闭图形数据库。
关闭图形数据库会导致断开连接并可能关闭底层存储后端,并释放此图形数据库占用的所有资源。关闭图形数据库需要关闭所有打开的独立于线程的事务,否则它们将被放弃。

   * failure to parse its arguments.  Only use this method when executing main from

   * or {@link #load(org.janusgraph.core.JanusGraph)}) when calling from
   * an enclosing application.
