Redefine Operation and Check for Exceptions
If the parent element of a selected operation is the source element for a Generalize connector, you can configure the operation to redefine an operation in the target element. Also, you can create code in your application to check for an exception and, if one occurs, to switch to the code defined by a Classifier element. You can identify the target operation and/or the classifier element on the Redefines tab.
