Watch is a very important mechanism in zookeeper, which can monitor the change of nodes in zookeeper and inform the client. Below, we use code as an example to analyze how watch is implemented in zookeeper. Zookeeper in a total of three ways to

As shown in, in Windows Explorer, the left sidebar is a wintree, and each node is an independent wintreeitem, such as system (C :), CDE, Dell, and so on.   It seems that CDE, Dell Is the child node of system (C :). However, when we use the coded

Background and purposeZookeeper in the development process encountered some common problems, in order to follow up development do not make the same mistake, summarize this kind of problem, and analyze and solve.Suitable for peopleIt is mainly

Watcher settings are the most common in development. You need to understand some basic features of watcher. Different watcher information is received for different operations on nodes of exists, getdata, and getchild. The change of the parent node

Watcher Setup is the most common development, need to understand some of the basic characteristics of watcher, for exists, GetData, getchild for the different operations of the node will receive different watcher informationstate=-112 Session

Let's continue with the previous one. We have some sleep :) (the German VS team last night was amazing). I still want to finish writing it. How can we implement the Select All TreeView function for All nodes today? How can we expand and collapse
