EMF Model Creation Wizards
Mindmap Model
, giving it whatever name you
want and selecting
Map
as the Model Object. The default EMF-generated editor
appears upon finish, ready for you to create new
Topic
and
Relationship
instances within the map.
You again need to open the Properties view to set model element properties
and establish subtopics and relationship links. Notice that validation is available
for our model instances and enforces the basic structural features defined in our
model. For example, we declared 1 for the
upper
and
lower bounds
on
source
and
target
references of our
Relationship
class. Creating a new
Relationship instance in our model and invoking the
Validate
menu option
brings up a dialog that points out that these required features were not set. As
we enhance our model further, EMF and the Validation Framework will provide
additional validation, as used by GMF for diagram validation.
