Hi,
If I define an extension point like this (Extension Point Creation Wizard):
- extension
'----- sequence
' '-----myPoint (1-*)
'----- point
'----- id
'----- name
- myPoint
'----- id (type = string)
'----- class (type = java)
'----- icon (type = resource)
'----- info (type = string)
If class is the user defined class (name) which extends an abstract class
(MyClass) that I defined.
I would like to know how can I get the informations entered by the user of
my extension point (id, icon, info) from the source code of the abstract
class (MyClass).
Thank you for any help.
And if you have links to any interresting documents about extension
points...

The following article explains just what I was looking for :
