Defining a stereotype as a metaclass

Defining a stereotype as a metaclass

You can promote a stereotype to metaclass status by selecting the Use as Metaclass check box in the stereotype property page. This can be useful when you need to:

Create new kinds of objects that share much of the behavior of an existing object type, such as business transactions and binary collaborations in a BPM for ebXML.
Have objects with identical names but different stereotypes in the same namespace (a metaclass stereotype creates a sub-namespace in the current metaclass).

Sub-objects
Stereotypes defined on sub-objects (such as table columns or entity attributes), cannot be turned into metaclass stereotypes.

To define a stereotype as a metaclass:

In the Stereotype property page, select the Use as metaclass check box

The new metaclass stereotype enjoys all the attributes of a standard metaclass:
- A separate list in the Model menu - the parent metaclass list will no longer display objects with the new metaclass stereotype. These objects will be displayed in the new list, which is displayed below the parent metaclass list.
  Objects created in the new list bear the new metaclass stereotype by default. If you change the stereotype, the object will be removed from the list the next time it is opened.
- Its own Browser folder and command in the New contextual menu.
- Property sheet titles based on the metaclass stereotype.
