The recent updates streamline error handling in the CompetencyRepository and LearningPathRepository by consolidating numerous custom query methods into unified access methods using getValueElseThrow. This refactoring improves code maintainability and readability, centralizing the handling of entity retrieval and associated exceptions.
Changes
| File | Change Summary |
|---|---|
CompetencyRepository.java |
Removed several custom query methods and replaced them with a generic getValueElseThrow method, simplifying the repository interface. |
LearningPathRepository.java |
Refactored error handling within default methods to use getValueElseThrow, enhancing code readability and maintainability. |

--- **Centralized exception handling approved.** The consistent application of `getValueElseThrow` across various methods ensures a uniform approach to error handling. The method is appropriately used in all relevant scenarios. - **Locations of `getValueElseThrow` usage:** - `CompetencyRepository.java` - `RepositoryImpl.java` - `ArtemisJpaRepository.java` - `LearningPathRepository.java` - `ProgrammingExerciseRepository.java` - `ComplaintRepository.java`--- `26-26`: **Centralized exception handling approved.** This change enhances maintainability by centralizing error handling. Ensure that `getValueElseThrow` is implemented correctly and efficiently handles all potential exceptions.Scripts executed
The following scripts were executed for the analysis: --- Script: ```shell #!/bin/bash # Description: Verify the appropriate usage of `getValueElseThrow` in all relevant scenarios. # Test: Search for the function usage.

--- **Centralized exception handling approved.** The implementations of `getValueElseThrow` in `RepositoryImpl` correctly handle exceptions by throwing `EntityNotFoundException` when the optional value is not present. This ensures efficient and consistent error handling across the repository methods. - `getValueElseThrow(Optionaloptional)`: ```java @NotNull public T getValueElseThrow(Optional optional) { return optional.orElseThrow(() -> new EntityNotFoundException(entityInformation.getEntityName())); } ``` - `getValueElseThrow(Optional optional, ID id)`: ```java @NotNull public T getValueElseThrow(Optional optional, ID id) { return optional.orElseThrow(() -> new EntityNotFoundException(entityInformation.getEntityName(), String.valueOf(id))); } ``` These methods effectively centralize the exception handling logic, enhancing maintainability and readability. --- `47-47`: **Centralized exception handling approved.** Using `getValueElseThrow` consistently across different methods aids in maintainability. Verify the performance implications of this method, especially in complex queries. --- `40-40`: **Centralized exception handling approved.** Continued use of `getValueElseThrow` promotes consistency and maintainability. Verify that it handles all edge cases correctly. --- `33-33`: **Centralized exception handling approved.** Consistent use of `getValueElseThrow` across methods enhances maintainability. Ensure that this method is used correctly in all scenarios where it's applied.Scripts executed
