本文整理了Java中org.apache.zookeeper.server.ZKDatabase.<init>()方法的一些代码示例,展示了ZKDatabase.<init>()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。ZKDatabase.<init>()方法的具体详情如下:
包路径:org.apache.zookeeper.server.ZKDatabase
类名称:ZKDatabase
方法名:<init>

ZKDatabase.<init>介绍

[英]the filetxnsnaplog that this zk database maps to. There is a one to one relationship between a filetxnsnaplog and zkdatabase.
[中]这个zk数据库映射到的文件txnsnaplog。filetxnsnaplog和zkdatabase之间存在一对一的关系。
