Their message is built from the required problem, solution to a problem, and unique identification number on the error message template. Individual errors have additional message parameters corresponding to the functionality. Range error has an additional minimum and maximum range that causes an error to be thrown or not thrown, and type error the type. The package contains prepared objects to manage the errors of the same type and multiple identification numbers, and their purpose is to set and throw errors under the given identification. Let's see what are the benefits. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
