[wtp-dev] JSDT: Life cycle of an infer engine

[Matthias Kempka <mkempka@xxxxxxxxxxxxxx>]

Hi,

I'm a bit confused about the life length - or maybe scope - of  
InferredType objects.

What I'm currently trying is to mix in the methods and attributes of  
mixins into classes. In general this works like this:

I have a mixin defined:

qx.Mixin.define("my.Mixin", {
   members : {
     foo : function() {}
  }
}

and I have a class that borrows the members of a Mixin like this:

qx.Class.define( "my.Class", {
   include : my.Mixin
}

If both definitions are in the same file, this is not a problem. But I  
got big problems if the Mixin is in a different file than the class.

The only way I'm aware of to get the InferredType object of the Mixin  
is to call "InferredType addType(char[])" in my InferEngine. If I do  
this, a new InferredType object is created for my.Class, and I never  
see the methods that where inferred during for my.Mixin. Also, even if  
I would get the identical object that contains the inferred members  
for my.Mixin, I could never be sure if it was inferred before my.Class  
or if it will be inferred somewhere later in the build cycle.

Am I missing something obvious here?

I would be content with creating a data structure that knows the  
correlations between mixins and classes, but to do this correctly I  
should know
a) when inferring a Mixin is completed (something like "2nd pass  
done") and
b) when a type inference for a project starts and ends.

Are there any plans to switch the inferrer to incremental inferencing?  
That would complicate this plan.

Regards,
Matthias
