Example: Creating a simple validator
219
subField
A String that specifies the name of the subfield associated with the
ValidationResult object.
In your override of the
doValidation()
method, you can define an empty Array and
populate it with ValidationResult objects as your validator encounters errors.
About the validate() method
You use the
Validator.validate()
method to programmatically invoke a validator from
within a Flex application. However, you should never override this method in your custom
validator classes. You need to override only the
validator classes. You need to override only the
doValidation()
method.
Example: Creating a simple validator
You can use the
StringValidator
class to validate that a string is longer than a minimum length
and shorter than a maximum length, but you cannot use it to validate the contents of a string.
This example creates a simple validator class that determines if a person is more than 18 years
old based on their year of birth.
