Examples of com.vaadin.data.validator.AbstractStringValidator

com.vaadin.data.validator.AbstractStringValidator
Validator base class for validating strings.
To include the value that failed validation in the exception message you can use "{0}" in the error message. This will be replaced with the failed value (converted to string using {@link #toString()}) or "null" if the value is null.

        // Postal code that must be 5 digits (10000-99999).
        tf = new TextField("Postal Code");
        tf.setColumns(5);


        // Create the validator - this would be even easier with RegexpValidator
        Validator postalCodeValidator = new AbstractStringValidator(
                "Postal code must be a number 10000-99999.") {
            @Override
            protected boolean isValidValue(String value) {
                return value.matches("[1-9][0-9]{4}");
