actualLocaleIDName:String [read-only] [override]

Language Version :

ActionScript 3.0

Product Version :

Flex 4.5

Runtime Versions :

Flash Player 10.1, AIR 2.5

The name of the actual locale ID used by this class object. This is the locale that is used to access the formatting data and functionality from the operating system.

If the locale that was set by the locale style is not available, then the value of the actualLocaleIDName is different from the value of the locale style. It indicates the fallback locale that is being used. If the locale style was set to LocaleID.DEFAULT the name of the locale specified by the user's operating system is used.

This property can be used as the source for data binding.

Implementation
public function get actualLocaleIDName():String

dateStyle:String

Language Version :

ActionScript 3.0

Product Version :

Flex 4.5

Runtime Versions :

Flash Player 10.1, AIR 2.5

The date style for this instance of the DateTimeFormatter. The date style is used to retrieve a predefined time and locale specific formatting pattern from the operating system. When formatting a date, the locale style, the timeStyle and the dateStyle properties determine the format of the date. The date style value can be set in the following two ways: assigning a value to either the dateStyle property or the dateTimePattern property.

The possible for this property are defined by the flash.globalization.DateTimeStyle class. Possible values for the dateStyle property are:

DateTimeStyle.LONG
DateTimeStyle.MEDIUM
DateTimeStyle.SHORT
DateTimeStyle.NONE
DateTimeStyle.CUSTOM

If the dateTimePattern property is assigned a value, as a side effect, the dateStyle property is set to DateTimeStyle.CUSTOM

The default value is DateTimeStyle.LONG.

This property can be used as the source for data binding.

Implementation
public function get dateStyle():String
public function set dateStyle(value:String):void

Throws

	`ArgumentError` — if the assigned value is not a valid `DateTimeStyle` constant or is `DateTimeStyle.CUSTOM`.

	`TypeError` — if the `dateStyle` or is set to `null`.

public function DateTimeFormatter()

Language Version :

ActionScript 3.0

Product Version :

Flex 4.5

Runtime Versions :

Flash Player 10.1, AIR 2.5

Constructs a new DateTimeFormatter object to format dates and times according to the conventions of the specified locale and the provided date and time formatting styles.

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

By using the class in an MXML declaration and inheriting the locale from the document that contains the declaration.

      <fx:Declarations> 
             <s:DateTimeFormatter id="df" />
      </fx:Declarations>

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

      <fx:Declarations> 
          <s:DateTimeFormatter id="df_Japanese" locale="ja-JP" />
      </fx:Declarations>

Calling the setStyle method. For example:
```
      df.setStyle("locale", "ja-JP")
```
Inheriting the style from a UIComponent by calling the UIComponent's addStyleClient() method.

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.

Most of the properties of this class are automatically set based on the locale style. If the locale style is changed, any properties that have not been explicitly set will also be updated based on the new locale. Note that the actual locale that is used is specified by the actualLocaleIDName property.

lastOperationsStatus

public function format(value:Object):String

Language Version :

ActionScript 3.0

Product Version :

Flex 4.5

Runtime Versions :

Flash Player 10.1, AIR 2.5

Formats a display string for an object that specifies a date in either the user's local time or UTC time.

A Date object has two sets of date and time values, those in the user's local time (date, day, fullYear, hours, minutes, month, and seconds) and those in UTC time (dateUTC, dayUTC, fullYearUTC, hoursUTC, minutesUTC, monthUTC, and secondsUTC). The boolean property useUTC controls which set of date and time components are used when formatting the date. The formatting will be done using the conventions of the locale as set by the locale style property and the dateStyle and timeStyle properties, or the dateTimePattern, specified for this DateTimeFormatter instance.

If there is an error when formatting, due to an illegal input value or other error, by default the format() method will return null. However if the errorText property is non-null, then the value of the errorText property will be returned. The lastOperationStatus property will be set to indicate the error that occurred.

Parameters

value:Object — A Date value to be formatted. If the object is not a Date then it will be converted to a date using the Date() constructor.

Returns

String — A formatted string representing the date or time value.
