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.

Method | Defined By | ||
---|---|---|---|
Constructs a new MatchingCollator object to provide string
comparisons according to the conventions of a specified locale. | MatchingCollator | ||
clearStyle(styleProp:String):void
Deletes a style property from this component instance. | AdvancedStyleClient | ||
compare(string1:String, string2:String):int
Compares two strings and returns an integer value indicating whether
the first string is less than, equal to, or greater than the second
string. | CollatorBase | ||
equals(string1:String, string2:String):Boolean
Compares two strings and returns a Boolean value indicating whether
the strings are equal. | CollatorBase | ||
getAvailableLocaleIDNames():Vector.<String> [static]
Lists all of the locale ID names supported by this class. | CollatorBase | ||
getClassStyleDeclarations():Array
Returns an Array of CSSStyleDeclaration objects for the type selector
that applies to this component, or null if none exist. | AdvancedStyleClient | ||
getStyle(styleProp:String):* [override]
Gets a style property that has been set anywhere in this
component's style lookup chain. | GlobalizationBase | ||
hasCSSState():Boolean
Returns true if currentCSSState is not null. | AdvancedStyleClient | ||
initialized(document:Object, id:String):void
The initialized method is called when this class or a class that
extends this class is used in an MXML declaration. | AdvancedStyleClient | ||
matchesCSSState(cssState:String):Boolean
Returns true if cssState matches currentCSSState. | AdvancedStyleClient | ||
matchesCSSType(cssType:String):Boolean
Determines whether this instance is the same as, or is a subclass of,
the given type. | AdvancedStyleClient | ||
notifyStyleChangeInChildren(styleProp:String, recursive:Boolean):void
Propagates style changes to the children of this style client
instance. | AdvancedStyleClient | ||
regenerateStyleCache(recursive:Boolean):void
Sets up the internal style cache values so that the
getStyle()
method functions. | AdvancedStyleClient | ||
registerEffects(effects:Array):void
Registers the EffectManager as one of the event listeners
for each effect event. | AdvancedStyleClient | ||
setStyle(styleProp:String, newValue:*):void
Sets a style property on this component instance. | AdvancedStyleClient | ||
styleChanged(styleProp:String):void
Detects changes to style properties. | AdvancedStyleClient | ||
stylesInitialized():void
Flex calls the stylesInitialized() method when
the styles for a component are first initialized. | AdvancedStyleClient |
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:
UIComponent
by calling the
UIComponent's addStyleClient method.Example: <fx:Declarations> <s:MatchingCollator id="mc" /> </fx:Declarations>
Example: <fx:Declarations> <s:MatchingCollator id="mc_France" locale="fr-FR" /> </fx:Declarations>
mc.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.
