Add element into collaboration
Newly identified elements (classes, objects, functions, variables, etc) must be added correctly into the collaboration, and
linked in the various relations. |
Add or refine operation
Add an operation to an object or class and/or refine it in terms of:
-
parameter list (name or type)
-
return value
-
pre-condition
-
post-condition
-
quality of service
|
Add or refine attribute
Add or refine an attribute in terms of:
|
Reify objects into a class
Abstract one or more objects into a class; for example, an elevator system contains Floor 1 UP button, Floor 1 DOWN button,
Floor 2 UP button, Elevator Destination Floor 1 button, etc, but only one Button class. |
Add or refine association
Associations are added between classes when instances of those classes must be able to send messages. They can be
refined in terms of:
-
directionality (unidirectional or bidirectional)
-
multiplicity
-
role end name
-
association name or label
-
association type
-
association
-
aggregation
-
composition
|
Add or refine generalization
Generalization is an "is-a-kind-of" relation. Generalization taxonomies can be constructed so that features (ports,
attributes, operations, states, transitions, associations, etc) are available to all subclasses. Refinement is usually an
adjustment of where in the taxonomy a class feature is introduced. |
Add or refine state behavior
Classes can specify state machines. State machines enforce ordering of the behavior of a Classifier. State machines can be
refined by adding or changing actions, transitions or states, by nesting of states, or adding sub-machines. In object
analysis, state machines normally grow organically as functionality is added to a class. |
Add or refine flow behavior
Flow of control is normally represented either with lines of code in the method body (simple case) or an activity diagram
(complex case). The activity diagrams can be refined by adding or changing flows, operators, actions, activities,
sub-activities, etc. Activity diagrams often grow organically as behavior is added to the class, rather than constructing
the algorithm in all its glory. |
