Re: [Zookeeper-user] visualize structure

[Stefan G. <sg...@10...>]

Thanks, I just wrote my own 10 liner, very helpful for development..
.. for the mail archive..

    public void showFolders(PrintStream out) throws IOException {
         int level =1 ;
         StringBuffer buffer = new StringBuffer();
         String startPath = "";
         addChildren(level, buffer, startPath);
         out.write(buffer.toString().getBytes());

     }

     private void addChildren(int level, StringBuffer buffer, String  
startPath) {
         ArrayList<String> children =  _zk.getChildren(startPath,  
false);
         for (String node : children) {
             buffer.append(getSpaces(level-1)+"'-" + "+" + node+"\n");

             addChildren(level + 1, buffer, startPath + "/" + node);
         }
     }

     private String getSpaces(int level) {
         String s = "";
         for (int i = 0; i < level; i++) {
             s += "  ";
         }
         return s;
     }

Results looks like this:

'-+katta
   '-+indexes
     '-+indexA
   '-+master
   '-+shard-to-salve
