Thanks for using Repast! We will look into fixing these issues in the
next release.

Subject: [Repast-interest] Interfaces & Inheritance within Symphony

Hi,

In order to improve the flexibility of my models, I like to make use of
interfaces to abstract from different possible implementations.
Thus, I define agents & contexts with interfaces + implementing classes.

The problem is that this approach doesn't fit very well with Repast
Symphony since the model score and the scenario entries require to
specify the concrete classes used.
If I want to change the implementation of a context or an agent, I've
almost nothing to do in my code, but then I've to update all the repast
files that was referencing the previous implementation ...
Moreover I've noticed that the scheduling annotation are processed only
if they are defined in a class which is used in model.score file.  
If there is a schedule annotation in a super class, this one is not
taken into account.

It would be nice to be able to reference interfaces / super classes in
the score file and in the scenario files, and so to be able to load
easily different implementations at run-time.
Do you think this is feasible?

To achieve this at the moment, I suppose I've to build the scenario with
java programming (but loosing the nice graphical interface ...).
Is there any documentation or code examples you can recommend me to have
a look at how to build a scenario in java ?

Thanks,
John
