Zookeeper Library for C + + encapsulation

Cppzk
---- Zookeeper Library for C + + encapsulation
Features:
1. C + + package, easy to use interface;
2. Fewer files, a header file and a source file, whether it is compiled into a library or direct source file compilation is very convenient;
3. Support the node's create, set, get, support watch;
4. Only Linux is supported for the time being.

Compile
The boost header file is required because boost::function is used as the callback function.

Under Linux:
CD src
Make-f makefile.mk
Generate LIBCPPZK.A


How to use

    #include "ZooKeeper.h"//contains header file        ZooKeeper ZK;//define Object    zk.init ("127.0.0.1:2181,127.0.0.1:2182,127.0.0.1:2183" );//Initialize, parameter is Zookeeper server address list, format: Ip:port,ip:port,...    Zk.exists (path);//Determine if the node exists    zk.createnode (path, data, recursive);//Recursive creation of nodes (Recursivce=false without recursive creation, Returns an error directly when the parent node does not exist)    Zk.createephemeralnode (path, data, recursive);//recursive creation of ephemeral nodes    Zk.createsequencenode ( Path, data, rpath, recursive); Recursive creation of the sequence node, rpath for the actual path returned    //watch    zk.watchdata (path, datacallback);//Watch node data, when the data changes, trigger callback function    Zk.watchchildren (path, childrencallback); Watch child node, when the child node is added or deleted, trigger callback function//    log    zk.setlogstream (stderr);//Set Log stream    Zk.setdebugloglevel (true); Turn on debug logging

The definition of Watch's callback:

    Two kinds of callback, data callback and child node callback    //Datawatchcallback return path and value of the path    //Childrenwatchcallback return path and sub-section name    under this path typedef boost::function<void (const std::string &path, const std::string &value) > datawatchcallback;    typedef boost::function<void (const std::string &path, const std::vector<std::string> &value) > Childrenwatchcallback;

For clarity, the above code omits the definition of error handling and some variables, and the complete code can be found in src/test.cc
