1"""Validator for correctly parsed values. 

2 

3When a value from the client (e.g. an integer) cannot be parsed by the field, 

4the field stores ``gws.ErrorValue`` instead. This validator fails for such 

5values, so that they are reported before the feature is written. 

6 

7Every field runs a default instance of this validator. A configured 

8``format`` validator replaces the default one, e.g. to set a custom message.

10Example:: 

11 

12 fields+ { 

13 name "count" 

14 type "integer" 

15 validators+ { type "format" message "Please enter a whole number" } 

16 }
