public Class MustMatchRegexExpression

This is a validator that, due to the addition of the parameter, allows the validation of multiple different types of input. The paramString must be a valid regular expression. The MustMatchRegularExpression validator will the String#matches(String) method on the string to be converted and the regular expression string and if the two do not match then a CsvValidationException will be thrown.

Because this is validating the string before it is parsed/converted, the capture settings of the string must be taken into account.

Examples:

    // The String that becomes id must be a number with three to six digits.
    @PreAssignmentValidator(validator = MustMatchRegexExpression.class, paramString = "^[0-9]{3,6}$")
    @CsvBindByName(column = "id")
    private int beanId;

    // The String that becomes bigNumber must be a number with seven to ten digits.
    // The String for this field is after the word "value: " in the field.
    @PreAssignmentValidator(validator = MustMatchRegexExpression.class, paramString = "^[A-Za-z ]*value: [0-9]{7,10}$")
    @CsvBindByName(column = "big number", capture = "^[A-Za-z ]*value: (.*)$", format = "value: %s")
    private long bigNumber;
