Index:
BankAccount
This type checks whether a bank account number is valid. You can use this validation on attributes of base type string.
Syntax
<type><locale>
Type - The type can be either 'bank' for bank account numbers or 'giro' for giro account numbers, or a combination 'bank/giro'.
Locale - Specify the country code for which you want to validate the bankaccount number, e.g. nl_NL for the Netherlands.
Examples
Assume you have added the validation type BankAccount with parameters <bank><nl_NL> to the attribute Client.BankaccountNr, then
Client.BankaccountNr = “123456789” is valid;
Client.BankaccountNr = “123456780” is invalid.
Assume you have added the validation type BankAccount with parameters <giro><nl_NL> to the attribute Client.BankaccountNr, then
Client.BankaccountNr = “P55555” is valid;
Client.BankaccountNr = “55555” is invalid.
IBAN
This type validates a string as International Bank Account Number (IBAN) performing a basic mod-97 calculation (ISO 7064) and country specific pattern checks. IBAN has no parameters.
Examples
“TN5910006035183598478831” validates as IBAN.
“TN5910006035183598478830” does not validate as IBAN.
the validator may return true for invalid bank account numbers. No bank specific account restriction checks are performed.
Date
Use this type to construct validations for specific date formats. You can use this validation on attributes that have base type date.
Syntax
<comparedate><comparator><compareday><comparemonth><compareyear>
comparedate - Compare the attribute value to a specific date, the dateformat of this date should be 'yyyy/MM/dd'.
comparator - The type of comparison, this can be 'less', 'equal' and 'greater'.
compareday - There are three options:
a number between 1 and 31; the day part of the attribute value is compared with this value.
'+' followed by a number; the day part of the attribute value is compared with the current day '+' the specified number.
'–' followed by a number; the day part of the attribute value is compared with the current day '–' the specified number.
comparemonth - There are three options:
a number between 1 and 12; the month part of the attribute value is compared with this value.
'+' followed by a number; the month part of the attribute value is compared with the current month '+' the specified number.
'–' followed by a number; the month part of the attribute value is compared with the current month '–' the specified number.
compareyear - There are three options:
a number; the year part of the attribute value is compared with this value.
'+' followed by a number; the year part of the attribute value is compared with the current year '+' the specified number.
'–' followed by a number; the year part of the attribute value is compared with the current year '–' the specified number.
Examples
Suppose that TODAY = 07-10-2004.
| Explanation | Validation rule |
|---|---|
| value = 01-02-2004 | <2004/02/01><equal> |
| value > 1 month from today | <><greater><><+1> |
| value < 1 year ago | <><less><><><-1> |
Number
This type checks the boundaries of an attribute with base type number, integer, currency or percentage.
Syntax
<maxIncl><minIncl><maxExcl><minExcl>
maxIncl - The attribute value should be less than or equal to this value.
minIncl - The attribute value should be greater than or equal to this value.
maxExc - The attribute value should be less than this value.
minExcl - The attribute value should be greater than this value.
Examples
| Parameters | Value | Result |
|---|---|---|
| <><0> | 0 | valid |
| <><><><0> | 0 | invalid |
| <><><><0> | 1 | valid |
| <120><><><0> | 120 | valid |
| <><><120><0> | 120 | invalid |
| <><><120><0> | 119 | valid |
| <5.1345><><><1.2345> | 5.1345 | valid |
| <5.1345><><><1.2345> | 1.2345 | invalid |
Regexp
This validation type checks whether a string value is part of a specified set of strings. You can use this type to validate a string as a correct postal code format, telephone number or email address.
Syntax
<posRegExp><negRegExp>
posRegExp - The attribute value should satisfy this regular expression.
negRegExp - The attribute value should not satisfy this regular expression.
The following characters are allowed in these regular expressions:
^[0-9]{4}\s{0,1}(?)[a-zA-Z]{2}$
The regular expressions used in several Blueriq Studio functions are common Java 1.4 expressions. For a complete documentation we refer to the online java documentation.
When writing regular expressions, you should make sure that they do not make the system vulnerable to ReDos attacks. The system can give a denial of service when an evil expression is used, that takes very long to evaluate by the parser.
Examples of evil regular expressions:
- (a+)+
- ([a-zA-Z]+)*
- (a|aa)+
- (a|a?)+
- (.*a){x} | for x > 10
The above are suspectible to aaaaaaaaaaaaaaaaaaaaaaaa!
It is difficult to give general rules that make sure that your expression is not evil, and even recognizing them can be hard. When writing regular expressions, consider Atomic Groups which help to avoid the evil behavior.
Examples
Postal code
<^[0-9]{4}( ?)[a-zA-Z]{2}$>
| Value | Result |
|---|---|
| “1000 AA” | valid |
| “1000AA” | valid |
| “10001AA” | invalid |
Telephone number
<(^\+[0-9]{2}|^\+[0-9]{2}\(0\)|^\(\+[0-9]{2}\)\(0\)|^00[0-9]{2}|^0)([0-9]{9}$|[0-9\-\s]{10}$)>
| Value | Result |
|---|---|
| “010 1234567” | valid |
| “+31(0)10 1234567” | valid |
| “010-1234567” | valid |
| “010 123456789” | invalid |
E-mail address
<^.+@[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,4})$><(@.*@)|(\.\.)|(@\.)|(\.@)|(^\.)|\s>
| Value | Result |
|---|---|
| “test@email.nl” | valid |
| “test@email.failure” | invalid |

SofiNumberValidator
This type checks whether a social security number is valid. You can use this validation on attributes that have base type string.
Syntax
<locale>
locale - Specify the country code for which you want to validate the social security number, e.g. nl_NL for the Netherlands.
Examples
Assume you have added the validation type SofiNumberValidator with parameter <nl_NL> to the attribute Client.SocialSecurityNr, then
Client.SocialSecurityNr = “123456782” is valid;
Client.SocialSecurityNr = “123456789” is invalid.
StringLength
This type validates the length of a string value.
Syntax
<minLength><maxLength>
minLength - The length of the attribute value should be greater than or equal to this value.
maxLength - The length of the attribute value should be less than or equal to this value.
Examples
| Parameters | Value | Result |
|---|---|---|
| <><5> | “john” | valid |
| <2><> | “a” | invalid |
| <4><8> | “username” | valid |
