All actions taken in the diagram tool that modify a part of the system are immediately reflected in the Eiffel system. Following is a summary of these actions.
|
|
* When you create a new class, this is the generated empty class: <br/>

class

|
CLASS_NAME
|
|
|
|
end -- class CLASS_NAME
|
|
</code>
|
|
|
|
* When you delete a class, the class file is removed from the disk.
|
|
* When you add a parent to a class, the parent is inserted in the existing inheritance clause, ''without'' any additional ( <code>undefine</code>/ <code>select</code>/etc.) clauses to solve possible conflicts. <br/>

* When removing an inheritance link, the entire parent clause is removed, i.e. including any <code>redefine</code>/<code>undefine</code>/etc. until the matching <code>end</code>.
|
|
* When creating a client link, a function or attribute is generated by the feature wizard. When creating a function, this code is generated: <br/>

* When removing a client link, only the matching function or attribute is removed. Any additionally generated set-feature or invariant is not removed.
|
|
* When removing a cluster, the associated directory is not erased, but the reference to the cluster is removed from the configuration file. At this time, it is not possible to create a cluster using the diagram tool, only to remove one.
