Custom exception classes serve as a way to handle specific error conditions in your Apex code. When these classes don’t follow proper naming
conventions, it creates several problems.
First, unclear naming makes code harder to understand and maintain. A class named MyError or CustomHandler doesn’t
immediately signal to other developers that it’s an exception class. This lack of clarity can lead to confusion when reading or debugging code.
Second, Apex follows Java conventions where exception classes should end with "Exception". This convention is widely recognized and expected by
developers. Breaking this convention makes your code inconsistent with established patterns.
Third, proper exception naming helps with code organization and searchability. When all exception classes follow the same naming pattern,
developers can quickly identify and locate them in the codebase.
Finally, some development tools and static analysis systems rely on naming conventions to provide better support, such as syntax highlighting, code
completion, and error detection.
What is the potential impact?
Poor naming conventions for exception classes can lead to:
- Reduced code readability and maintainability
- Confusion for team members and future developers
- Inconsistency with Apex and Java conventions
- Difficulty in identifying exception classes during code reviews
- Potential issues with development tools that rely on naming patterns
