Examples of net.mygwt.ui.client.data.Model

net.mygwt.ui.client.data.Model
Models are generic data structures that notify listeners when changed. The structure allows a form of 'introspection' as all property names and values can be queried and retrieved at runtime.
Model objects implement the IsSerializable and can therefore be used with GWT RPC. A model's children are not marked transient and will be passed in remote procedure calls.

Events:

Model.Add, Model.Insert, Model.Remove, Model.Update

@see ChangeListener @see IsSerializable
