Hierarchical VOs

[jonbonbon]

Hi, this is my first post so excuse the noob question. Still trying to get my head around the framework.
Also this might be more related to AS3 in general.. not sure...

I have a hierarchical set of data that I need to represent in the model. The structure looks like this:

-- set of shapes
---- shape
------ shape id
------ shape name
------ shape colour
------ set of coordinates
-------- coordinate
---------- x
---------- y

I've created one proxy and three VOs:

ShapeDataVO - contains an array of ShapeVOs
ShapeVO - conatins shape details and an array of CoordinateVOs
CoordinateVO - conatins x y coordinates

The proxy is responsible for providing an API for all three VOs.

Is it good practice to have more than one VO to a proxy?
Perhaps I should create one VO that somehow represents the full data on its own?

Thanks in advance for any help!

Hi,

The proxy could have just the ShapeDataVO. The ShapeDataVO has getters like:

- getAllShapes():Vector.<ShapeVO>
- getShapeByID():ShapeVO

The ShapeVO has a getter to return CoordinateVO's:

- getCoordinates():Vector.<CoordinateVO>

I would search the forums for "SmartVO"

Best,
Sammi

Thanks sammi that makes much better sense!
