Schema data types
A data type is an object that represents all the runtime logic needed to support a particular
data type. A data type can be a scalar type, such as integer, string, date, currency amount, or
ZIP code. It can also be a complex type, with subfields and so on. A data type can test a data
value to determine if it is valid for that data type. The following data types come with Flash
MX Professional 2004 and Flash Professional 8:
Array No validation options.
Attribute XML attribute. No validation options.
Boolean No validation options.
Custom Lets you add a custom class to check for this special kind of validation. Your code
should call the validate function when the field is assigned a new value, inspect the value, and
determine whether it’s valid. If it is, the function should simply return. If not, the function
should call
this.ValidationError(“some informative message”);. The custom class
must be in the classpath and formatted as shown in the following example:
class myCustomType extends mx.databinding.CustomValidator {
function validate(value) {
... some code here
}
}
DataProvider
No validation options.
Date No validation options.
DeltaPacket No validation options.
Integer A validation option can be set up to define the minimum and maximum values.
Number A validation option can be set up to define the minimum and maximum values.
Object No validation options.

String A validation option can be set up to define the minimum and maximum number of

XML Lets you specify if white space should be ignored when a string is converted into
XML.
ZipCode No validation options.
