Class: RegExpValidator ​

Defined in: reg-exp.ts:13

Regular expression validator. The regular expression applies to the full string only if constructed as such. For example, /\d*/ (0 or more digits) matches every string, /\d+/ (1 or more digits) matches strings with at least one digit, /^\d*$/ matches strings that are all digits or empty, and /^\d+$/ matches strings that are all digits and not empty.

Clients of this class are recommended to override the createErrorMessage method create a more suitable error message for their use case.
