Validating uml models and ocl constraints notsoseriousdatingsite com
For example, the automatic layout can be turned off, the layout of the diagram can be saved and restored from a file, etc.In the previous picture we have turned on the display of attribute values.Objects can be created by selecting a class and specifying a name for the object.The menu command And, even simpler, an object can be created via drag & drop.use At this point you can enter commands at the prompt (try 'help' for a list of available commands).For example, you can enter OCL expressions by starting the input with a question mark.By default both interfaces are launched (unless you specify the switch On the left is a tree view showing the contents (classes, associations, invariants, and pre- and postconditions) of the model.The next picture shows the expanded tree with all model elements.
A context menu available on a right mouse click in the object diagram provides several display options.
The expression will be evaluated and its result will be shown, e.g.: The command line interface is useful for experienced users and for automated validation procedures since commands can be read from a script file.
The graphical user interface is easier to learn and provides different ways of visualizing a system state.
The constraints are first given in natural language and will later be expressed more formally in OCL (Object Constraint Language).
Constraints: The goal of applying the USE tool is to interactively validate the above model and the constraints.
