Generating the source code

This section is the result of a cut & paste of the comment at the beginning of codegen/py_codegen.py. It is *VERY* incomplete. The ContentHandler subclass which drives the code generation is xml_parse.CodeWriter.

How the code is generated: every time the end of an object is reached during the parsing of the xml tree, either the function add_object or the function add_class is called: the latter when the object is a toplevel one, the former when it is not. In the last case, add_object calls the appropriate ``writer'' function for the specific object, found in the obj_builders dictionary. Such function accepts one argument, the CodeObject representing the object for which the code has to be written, and returns 3 lists of strings, representing the lines to add to the __init__, __set_properties and __do_layout methods of the parent object.

Note

The lines in the __init__ list will be added in reverse order.
