This function allows you to extend the functionality of all a2dCanvasObject classes in a a2dCanvasDocument, without adding extra members to these objects.
Default functions are called on the a2dWalkerIOHandler, which redirect the calls to other functions based on this object its classname. On can register classes to a2dWalkerIOHandler or derived classes. This way for each unique object in the document there can be a function in a2dWalkerIOHandler.
- Returns:
- false if some object did not have a function attached via a2dWalkerIOHandler.
Reimplemented from a2dCanvasObject.
