mx.formatters.ZipCodeFormatter (Flex 4 Beta)

Package	mx.formatters
Class	public class ZipCodeFormatter
Inheritance	ZipCodeFormatter Formatter Object

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The ZipCodeFormatter class formats a valid number into one of the following formats, based on a user-supplied formatString property.

#####-####
##### ####
#####
### ### (Canadian)

A six-digit number must be supplied for a six-digit mask. If you use a five-digit or a nine-digit mask, you can use either a five-digit or a nine-digit number for formatting.

If an error occurs, an empty String is returned and a String that describes the error is saved to the error property. The error property can have one of the following values:

"Invalid value" means an invalid numeric value is passed to the format() method. The value should be a valid number in the form of a Number or a String, except for Canadian postal code, which allows alphanumeric values, or the number of digits does not match the allowed digits from the formatString property.
"Invalid format" means any of the characters in the formatString property do not match the allowed characters specified in the validFormatChars property, or the number of numeric placeholders does not equal 9, 5, or 6.
