Class LinkedCourseValidator

java.lang.Object

edu.ucsb.cs156.frontiers.validators.LinkedCourseValidator

All Implemented Interfaces:

jakarta.validation.ConstraintValidator<HasLinkedCanvasCourse,Course>

public class LinkedCourseValidator
extends Object
implements jakarta.validation.ConstraintValidator<HasLinkedCanvasCourse,Course>

This is a validator, which enforces a property. These are used together with @Validated to in a spring managed bean (for example, a controller or service).

With this validator, you would have to put lots of code in your controller to check for linked courses. Instead, we can just put @HasLinkedCanvasCourse on the method parameters that require it, and if the contraint is not satisfied, a ConstraintViolationException will be thrown.
