This class defines which data proxy to use for binding diagram object with application data object.
Data binding from diagram objects to application data uses proxies.
To enable binding, a developer must create sprite proxy classes implementing ISpriteProxy interface and link proxy classes implementing ILinkProxy interface.
Then he must create a XML configuration document that links spriteid, links and proxies.
Then he must create a DiagramModel with the XML configuration document and define it as the model of the DiagramView.
When this plumbery is done, everytime a sprite or a link is created, deleted or changed, the corresponding method of the corresponding proxy is called.
On the opposite it is the responsibility of the developer to implements application data manipulation so that application data reflects the states of the diagram.
Example
This sample show how to define a model.
MyFirstObjectProxy and
MySecondObjectProxy implements
ISpriteProxy,
MyLinkProxy implements
ILinkProxy,
MyLaneProxy and
MyPanelProxy implements
IObjectProxy.
