The SortingCollator class provides locale-sensitve string comparison capabilities with inital settings suitable for linguistic sorting purposes such as sorting a list of text strings that are displayed to an end-user.

This class is a wrapper class around the flash.globalization.Collator. Therefore the locale-specific string comparison is provided by the flash.globalization.Collator. However, this SortingCollator class can be used in MXML declartions, uses the locale style for the requested Locale ID name, and has methods and properties that are bindable. Additionally, LastOperationStatus is set, if there is an error or warning generated by the flash.globalization class.

The flash.globalization.Collator class uses the underlying operating system for the formatting functionality and to supply the locale specific data. On some operating systems, the flash.globalization classes are unsupported, this wrapper class provides a fallback functionality.

Constructs a new SortingCollator object to provide string comparisons according to the conventions of a specified locale.

This class sets the initial values of the various collation options for general linguistic sorting usages such as sorting a list of text strings that are displayed to an end user. In this mode, differences in uppercase and lowercase letters, accented characters, and other differences specific to the locale are considered when doing string comparisons.

The comparison provided by an instance of this class is equivalent to constructing an instance of the flash.globalization.Collator with the initialMode paramater set to CollatorMode.SORTING. For more details and examples of this mode, please see the documentation for the flash.globalization.Collator class.

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.
```
      Example:
      <fx:Declarations>
             <s:SortingCollator id="sc" />
      </fx:Declarations>
      
```

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

      Example:
      <fx:Declarations>
          <s:SortingCollator id="sc_France" locale="fr-FR" />
      </fx:Declarations>

Calling the setStyle method, e.g. sc.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.
