The NumberValidator class ensures that a String represents a valid number according to the conventions of a locale. It can validate strings that represent int,uint, and Number objects.

This class uses the locale style for specifying the requested locale ID.

The validator can ensure that the input falls within a given range (specified by minValue and maxValue properties), is an integer (specified by domain property), is non-negative (specified by allowNegative property), correctly specifies negative and positive numbers, and does not exceed the specified number offractionalDigits. The validator sets default property values by making use of the flash.globalization.NumberFormatter and therefore the locale specific values are supplied by the operating system.

The NumberValidator class can be used in MXML declarations or in ActionScript code. This class uses the locale style for specifying the requested Locale ID required by the flash.globalization.NumberFormatter class, and has methods and properties that are bindable.

A numeric value that indicates a validating pattern for negative numbers. This pattern defines the location of the negative symbol or parentheses in relation to the numeric portion of the number to be validated.

The following table summarizes the possible formats for negative numbers. When a negative number is validated, the minus sign represents the value of the negativeSymbol property and the 'n' character represents numeric value.

Negative number format type	Format
0	(n)
1	-n
2	- n
3	n-
4	n -

The default value is dependent on the actual locale and operating system.

Constructs a new NumberValidator object to validate numbers according to the conventions of a given locale.

The locale for this class is supplied by the locale style. The locale style can be set in several ways:

Inheriting the style from a UIComponent by calling the UIComponent's addStyleClient method.
By using the class in an MXML declaration and inheriting the locale from the document that contains the declaration.
```
      <fx:Declarations>
             <s:NumberValidator id="nv" />
      </fx:Declarations>
      
```

By using an MXML declaration and specifying the locale value in the list of assignments.

      <fx:Declarations>
          <s:NumberValidator id="nv_French_France" locale="fr_FR" />
      </fx:Declarations>

Calling the setStyle method. For example: nv.setStyle("locale", "fr-FR")

If the locale style is not set by one of the above techniques, the instance of this class will be added as a StyleClient to the topLevelApplication and will therefore inherit the locale style from the topLevelApplication object when the locale dependent property getter or locale dependent method is called.

Convenience method for calling a validator from within a custom validation function. Each of the standard Flex validators has a similar convenience method. Caller must check the ValidationResult objects in the returned array for validation status.

매개 변수

	`value:Object` — A number string to validate.

	`baseField:String` — Text representation of the subfield specified in the `value` object. For example, if the `value` parameter specifies value.number, the `baseField` value is "number".

반환값

Array — An Array of ValidationResult objects, with one ValidationResult object for each field examined by the validator.
