[Swig-user] SWIG generated methods and additional code injection

[Karol L. <kar...@gm...>]

Hello,

Is there a way to inject additional code to a specific SWIG(v2.0.11)
generated methods in C# (filtered by method name and class)?
I'm currently in battle with the C# Garbage collector and done as described
at http://www.swig.org/Doc2.0/CSharp.html#CSharp_memory_management_objects
(with success).
Now I'm trying to create a more generic solution by injecting additional
code to the troublesome functions.
For example I have a bunch of register and unregister methods (class
UserModel):

 public virtual bool RegisterAffectionModel(AffectionModel affectionModel) {
      [SWIG generated Code]
 }

 Now what I'm trying to achieve is:

 public virtual bool RegisterAffectionModel(AffectionModel affectionModel) {
    [SWIG generated Code]
    registerElementReference(affectionModel);
 }

  public virtual bool UnregisterAffectionModel(AffectionModel affectionModel)
{
    [SWIG generated Code]
    unregisterElementReference(affectionModel);
 }

I've achieved a partial success by using typemap csin and the "pre"
attribute. But by using this approach I cannot filter the injection to a
specific methods.
I understand that there is a workaround for as similar problem as described
at http://swig.10945.n7.nabble.com/Apply-typemap
-to-single-method-td11684.html.
But maybe a more cleaner solution was created since then?

Thanks
Karol
