The MatchingCollator class provides locale-sensitve string comparison capabilities with inital settings suitable for general string matching such as finding a matching word in a block of text.

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 MatchingCollator 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.

Constructor Detail
MatchingCollator()Constructor
public function MatchingCollator()

Language Version : ActionScript 3.0
Product Version : Flex 4.5
Runtime Versions : Flash Player 10.1, AIR 2.5

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

This class sets the initial values of the various collation for general string matching uses such as determining if two strings are equivalent or finding a matching word in a block of text. In this mode, differences in uppercase and lower case letters, accented characters, and so on are ignored 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.MATCHING. 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:

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.
