[Opensim-dev] Dynamic attributes

[Mic Bowman]

Justin,

I took a look at the DAMap data structure & have some questions. What's the
value of explicit methods for the top level of the structure? It is still
possible to have name space collisions since there is nothing that prevents
one module from writing into another module's "name space". Also, whats
your expectation for locking? The top level accessor locks the structure,
but modules that share the rest of the structure will have to do their own
locking anyway. I guess one value of controlling the top level is that *IF*
modules are making exclusive access to the structure, the locking is
minimized. Hard to control that, though.

Did you get a chance to look at the JsonStore structure? The path-based
accessors are very different than providing immediate access to the OSDMap.
As we discussed, I made that decision to support the synchronization
operations (take & read) and it removes the exposed OSDMap so that the data
structure can be replaced. I think the path-based accessor is probably too
heavyweight for DAMap... well... maybe... given that we dont have any
examples yet its hard to tell. :-)
