validateValue method

  1. @mustCallSuper
void validateValue(
  1. bool value
)
inherited

Validates the parsed value, throwing a FormatException if the value is invalid, or a UsageException if the value is invalid for other reasons.

Subclasses may override this method to perform specific validations. If they do, they must also call the super implementation.

Implementation

@mustCallSuper
void validateValue(final V value) {
  if (allowedValues?.contains(value) == false) {
    throw UsageException(
        '`$value` is not an allowed value for ${qualifiedString()}', '');
  }

  customValidator?.call(value);
}
