Using Roassal
Roassal is part of Moose
You have nothing to install
A tutorial is available on u-cursos and online
http://bergel.eu/download/Mondrian.pdf
Getting MSE file
MSE is the file format used to exchange meta-models
In order to load a Java application into Moose, you need first to translate your .java files into a MSE file
VerveineJ is a translator Java -> MSE

Roassal contains many examples
Tarea
Tarea A
You will conduct an analyze of an application
You need to hand in a small report on Thursday 11 April
This time using the tools we introduced today
You need to provide a report that contains:
a description of a software
analysis of the software using the visualizations and tools we have seen today
use Roassal / Mondrian to do a personal visualization
suggestion for code improvement
