2.1.2 Modifying existing object types
To open the specification of an existing object type in an
Object Tool:
| 1a) | If
you have an Object Tool open already, press the Open toolbar button (or
select Object | Open... from the menu bar) and select the desired object
type from the
list. |
| 1b) | To open
an Object Tool for a given object type you can select that type from the
Metamodel Browser, Type Browser or Graph Tool lists of object types, and double
click it or choose Edit Type from the list’s pop-up
menu. |
The Object Tool
supports all the basic functionality needed for maintaining object types: you
can add new properties, change local names, or even substitute old property
types with new ones, through the right button pop-up menu in the properties
list.
You can also change the name of the object type: note that
changing the type name affects all places where this object type is used. The
description, dialog and symbol of the type can also be modified.
| 2) | Press
the Save button after performing the modifications
to save the changes to the object type.
|
Important notice! Before pressing
modify and at least before committing the transaction, be sure to know that you
want the modifications to take place, because they affect all the models where
this object type is used. You should also think before changing the types that
were delivered with MetaEdit+, because if you modify them, we cannot guarantee
that you can use later upgrades to these modeling languages. If you want to
modify the existing modeling languages, you could make descendants of the types
instead of changing the types themselves.
