[Opensim-dev] Add a JsonTestStore() for the JSON store module?

[Mic Bowman]

I think that would be very useful. I can add it this afternoon, if you
don't beat me to it.

When I wrote the interface to the Json store, I modeled the path expansion
after JQuery interface. However, I'm finding that really challenging to use
for iterating through an array of values. Right now, I use osFormatString
to create the path dynamically. For example:

integer i = 0;
while (i < 10)
{
    string p = osFormatString("foo[{0}].bar",[i]); // create path
"foo[0].bar"
    string v = JsonGetValue(storeID,p);
}

If you have any suggestions for a construct that would make the iteration
cleaner, I would be very interested. I've bounced around (and written some
test code) for taking a list (the components of the path) as an argument,
but constructing the list is no easier than constructing the string. I've
also poked around with creating store handles that point into an existing
store (so you resolve the path "foo" into a store handle then iterate at
the top level). Again, the code to walk through the structure is still
excessively complex.
