Exception (dictionary item)

Model Parts, Diagrams, Dictionary Items, and Properties > Dictionary items > Exception (dictionary item)

For automation interface information about an Exception, see Exception (automation interface).

Exceptions are called by Operations, and are used to indicate alternative courses of action if Operations are not performed successfully. Exceptions contain a number of parameters, which are used to transmit or receive data from Operations.

An Exception can be assigned as a data type for an Attribute, Operation, Parameter or Type Definition.

You can create an Exception through the context menu of a Package: right-click the item, and select New > UML > Behavior > Exception. You can also create an Exception from the context menu of a Class or Signal: right-click the item, and select New > Exception.

In the Modeler panes, a short-cut symbol

on the Exception's icon indicates that the item is a stub.

The following sections provide information about how an Exception is used in the model. For more information about a property, item, model part or diagram, click it.
