22-22: Review of importsThe import statements are correctly added to support the new functionalities. The use of
ErrorDescriptionandCollectorsis appropriate for the operations performed in the methods.

Add utility method for running all validators
The newly added validate method effectively encapsulates the validation logic, making it more maintainable and reusable. This method adheres to the objectives outlined in the linked issue and PR description by simplifying the validation process.
However, there's a potential type safety issue with the unchecked cast in line 36. It's generally safe here because this is an instance of ValidationSupport<T>, but it's still a good practice to avoid explicit casts when possible, as they can lead to ClassCastException if assumptions about types are incorrect.
- List<Validator<T>> validators = ((ValidationSupport<T>) this).getValidators(validatorType);
+ List<Validator<T>> validators = this.getValidators(validatorType);Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Refinement of getValidators method
The method getValidators(Class<? extends Validator> validatorType) is a good addition for filtering validators of a specific type. This implementation uses Java's streams effectively. However, consider using Class<? extends Validator<T>> instead of Class<? extends Validator> for better type safety and to ensure that the validators are compatible with the generic type T.
- default List<Validator<T>> getValidators(
- @SuppressWarnings("rawtypes") Class<? extends Validator> validatorType) {
+ default List<Validator<T>> getValidators(
+ Class<? extends Validator<T>> validatorType) {
return getValidators().stream().filter(validatorType::isInstance).collect(Collectors.toList());
