Annotation Type ImmutableValidator


  • @Retention(SOURCE)
    @Target(METHOD)
    public @interface ImmutableValidator
    Annotation defining which method is to be used to validate the bean when code generating immutable beans.

    Each property in a bean can be independently validated. This annotation allows properties to be cross-checked at the end of the constructor.

    The method must be a private void instance method and take no arguments. Private is necessary as it is called from the constructor. For example:

       @ImmutableValidator
       private void validate() {
         if (age != null && age < 0) {
           throw new IllegalArgumentException("Age must not be negative if specified")
         }
       }
