I have
XML files that are representation of a portion of HTML code.
Those
XML files also have widget declarations.
Example
XML file:
<message id="msg">
<p>
<Widget name="foo" type="SomeComplexWidget" attribute="value">
inner text here, sets another attribute or
inserts another widget to the tree if needed...
</Widget>
</p>
</message>
I have a main Widget class that all of my widgets inherit from.
The question is how would I create it?
Here are my options:
Create a compile time tool that will parse the
XML file and create the necessary code to bind the widgets to the needed objects.
Advantages:
No extra run-time overhead induced to the system.
It's easy to bind setters.
Disadvantages:
Adds another step to the build chain.
Hard to maintain as every widget in the system should be added to the parser.
Use of macros to bind the widgets.
Complex code
Find a method to register all widgets into a factory automatically.
Advantages:
All of the binding is done completely automatically.
Easier to maintain then option 1 as every new widget will only need to call a WidgetFactory method that registers it.
Disadvantages:
No idea how to bind setters without introducing a maintainability nightmare.
Adds memory and run-time overhead.
Complex code
What do you think is better? Can you guys suggest a better solution?
