Examples of net.xoetrope.xui.data.XModel

net.xoetrope.xui.data.XModel
The XModel is designed to support an MVC like structure. The model allows data to be maintained separately from UI code and separately from the control logic. The model supports an XPath like way of naming nodes and accessing data. The model is hierarchical and therefore a variety of data can be stored including simple scalar values to vectors and arrays. The model can be supplemented by adding custom node types and by using adapters and bindings.
The XModel is one of the main ideas behind XUI and central to providing the clean separation of the data. The XUI UI components can be abstractly bound to the model as instances of XModel although the actual nodes may be implemented by a range of classes representing tables or lists of even more complex nodes. All the UI component need know the path to the node in the model.
In some cases an adapter is used to simplify access to the data and perhaps maintain additional information needed by the UI component (e.g. the selected value in a list).
