3.11.2 Error Handling

The procedure goops-error is called to raise an appropriate error by the default methods of the following generic functions:

• slot-missing (see section slot-missing)
• slot-unbound (see section slot-unbound)
• no-method (see section no-method)
• no-applicable-method (see section no-applicable-method)
• no-next-method (see section no-next-method)

If you customize these functions for particular classes or metaclasses, you may still want to use goops-error to signal any error conditions that you detect.

procedure: goops-error format-string . args

Raise an error with key goops-error and error message constructed from format-string and args. Error message formatting is as done by scm-error.
