Edward Ribeiro commented on ZOOKEEPER-3035:
-------------------------------------------
Please, don't open Jira issues to ask questions. Use ZK mailing lists (user
and/or dev) to ask such things.
The OpCode is the number that identifies a given operation (getData, setData,
exists, etc) on the wire protocol. When the message is serialized/deserialize
the value tells what kind of message it is.

> I'm reading the source code, but I often can not understand the operation
> code mean in OpCode.java. For example , the sync operation code is 9, but I
> can't understand what does this mean, and the source code has nothing about
> the code description. Do we have some wiki or document abount operation code?
> {code:java}
> public interface OpCode {
> public final int notification = 0;
> public final int setACL = 7;
> public final int getChildren = 8;
> public final int sync = 9;
> public final int ping = 11;
> }
