Exceptions handling tool

This Exceptions handling tool is used to specify whether the debugger stops or continues on specific exceptions.

To access this tool, follow the menu path:

Execution --> Exception handling

Note: Now that exceptions are objects in Eiffel, the mechanism is unified for classic and .NET systems, using the Eiffel exception class names.

Tailoring exception handling behavior

The image below shows the Exceptions handling tool.

In the top two checkboxes, the tool provides a way to enable and disable "Catcall" warnings on the console or in the debugger.

If the "filter exceptions" checkbox is enabled, for each exception you can specify the exception action as one of:

• Disabled means that filtering for this exception is not enabled. Therefore, the default behavior of Catch applies.
• Catch means stop on such an exception.
• Ignore means do not stop on such an exception.

You can double clicking an exception name to toggle its status between Ignore and Catch.

Clicking the button labeled Ignore External Exception? will set the status of a set of external exceptions to Ignore.

Click the button labeled Apply to apply your selections, or Reset to reset the tool to its default values.

Tip: Using the "Pattern" field, you can add your own filters using regular expression.
