> Following up on my conversations with Patrick and Mahadev (http://n2.nabble.com/Might-I-contribute-a-Node-design-for-the-Java-API-td4567695.html#a4567695).
> This patch includes the implementation as well as unit tests. The first unit test gives
a simple high level demo of using the node API.
> The current implementation is simple and is only what I need withe current project I
am working on. However, I am very open to any and all suggestions for improvement.
> This is a proposal to support a simplified node (or File) like API into a Zookeeper tree,
by wrapping the Zookeeper Java client. It is similar to Java's File API design.
> Although, I'm trying to make it easier in a few spots. For example, deleting a Node recursively
is done by default. I also lean toward resolving Exceptions "under the hood" when it seems
appropriate. For example, if you ask a Node if it exists, and its parent doesn't even exist,
you just get a false back (rather than a nasty Exception).
> As for watches and ephemeral nodes, my current work does not need these things so I currently
have no handling of them. But if potential users of  the "Node a.k.a. File" design want these
things, I'd be open to supporting them as reasonable.
