| Interface | Description |
|---|---|
| DerivedPropertyNotifier |
Used to observe and filter for model changes that affect derived properties
defined by OCL expression.
|
| ImpactAnalyzer |
The Impact Analyzer (IA) analyzes the impact of
Notifications on a single OCLExpression in the sense that it
determines those context objects of the expression for which the expression's evaluation result may have changed because of the
change indicated by the notification. |
| ImpactAnalyzerFactory |
Used to create
ImpactAnalyzer and DerivedPropertyNotifier
objects. |
| PartialEvaluator |
A partial evaluator can be used to evaluate an expression at a hypothetical model
state as it has been before a change, as described by an EMF
Notification,
has taken place. |
| PartialEvaluatorFactory |
Used to create
PartialEvaluator objects. |
| Class | Description |
|---|---|
| Revalidator |
Use to react to model changes within a
ResourceSet affecting the OCL-specified
constraints / invariants provided by one or more EPackages. |
| Exception | Description |
|---|---|
| ValueNotFoundException |
Thrown when during (partial) OCL evaluation the value of a yet undefined variable is requested
from the
