  • Method Details

    • initialize

      public void initialize(Size parameters)
      Description copied from interface: ConstraintValidator
      Initializes the validator in preparation for ConstraintValidator.isValid(Object, ConstraintValidatorContext) calls. The constraint annotation for a given constraint declaration is passed.

      This method is guaranteed to be called before any use of this instance for validation.

      The default implementation is a no-op.

      Specified by:
      initialize in interface ConstraintValidator<Size,CharSequence>
      Parameters:
      parameters - annotation instance for a given constraint declaration

    • isValid

      public boolean isValid(CharSequence charSequence, ConstraintValidatorContext constraintValidatorContext)
      Checks the length of the specified character sequence (e.g. string).
      Specified by:
      isValid in interface ConstraintValidator<Size,CharSequence>
      Parameters:
      charSequence - The character sequence to validate.
      constraintValidatorContext - context in which the constraint is evaluated.
      Returns:
      Returns true if the string is null or the length of charSequence between the specified min and max values (inclusive), false otherwise.
