Hello,
I am new to Google Wave API and would like to ask a question about
Google Wave persistence layer,
My use case is that I want to reprensent a tree structure in a google
wave gadget and a group will work collaboratively on curating the tree
structure e.g. editing a node, adding a sub node or deleting a node.
Assuming the tree structure is based on a json object, my question is
whether there is a persistence layer API to store and restore a json
object,
>From the tutorial, I can see a submitDelta() which is used to save a
key-value pair representing an update. Is it possible that the value be
a json object?
>Updates the state object with delta, which is a map of key-value pairs
representing an update. For example,
>wave.getState().submitDelta({'count': 5}) sets the value of the count
key to 5.
By the way, do you know whether there is a wave gadget already developed
for this use case?
Thanks,
-Guoqian
