[OpenLayers-Users] Overwrite and extend initialize function of a class

[Armin Burger]

Hi all

I would like to overwrite and extend the "initialize" function of a 
class. For all other functions I used the method via

OpenLayers.My_CLASS.prototype.funtionToOverWrite = function() {

but in the case of the initialize function this does not show any effect 
(it is not used). OL version used is 2.11

In addition I would not like to completely rewrite the function but 
extend it. I mean, calling the original function and then adding a few 
lines of code afterwards. Is this possible? If I create a new class 
inheriting from another I just can call the parent class like

OpenLayers.Control.Parent_Class.prototype.initialize.functionToExtend(this,...);

and add my code afterwards. But this does not work when modifying an 
existing class.

Any ideas how to achieve these goals?

Thanks in advance for any hints
Armin
