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.

Method | Defined By | ||
---|---|---|---|
Constructs a new SortingCollator object to provide string comparisons
according to the conventions of a specified locale. | SortingCollator | ||
addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registers an event listener object with an EventDispatcher object so that the listener
receives notification of an event. | EventDispatcher | ||
Deletes a style property from this component instance. | AdvancedStyleClient | ||
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 | ||
Dispatches an event into the event flow. | EventDispatcher | ||
Compares two strings and returns a Boolean value indicating whether
the strings are equal. | CollatorBase | ||
[static]
Lists all of the locale ID names supported by this class. | CollatorBase | ||
Returns an Array of CSSStyleDeclaration objects for the type selector
that applies to this component, or null if none exist. | AdvancedStyleClient | ||
[override]
Gets a style property that has been set anywhere in this
component's style lookup chain. | GlobalizationBase | ||
Returns true if currentCSSState is not null. | AdvancedStyleClient | ||
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | EventDispatcher | ||
Indicates whether an object has a specified property defined. | Object | ||
The initialized method is called when this class or a class that
extends this class is used in an MXML declaration. | AdvancedStyleClient | ||
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | ||
Returns true if cssState matches currentCSSState. | AdvancedStyleClient | ||
Determines whether this instance is the same as, or is a subclass of,
the given type. | AdvancedStyleClient | ||
Propagates style changes to the children of this style client
instance. | AdvancedStyleClient | ||
Indicates whether the specified property exists and is enumerable. | Object | ||
Sets up the internal style cache values so that the
getStyle()
method functions. | AdvancedStyleClient | ||
Registers the EffectManager as one of the event listeners
for each effect event. | AdvancedStyleClient | ||
Removes a listener from the EventDispatcher object. | EventDispatcher | ||
Sets the availability of a dynamic property for loop operations. | Object | ||
Sets a style property on this component instance. | AdvancedStyleClient | ||
Detects changes to style properties. | AdvancedStyleClient | ||
Flex calls the stylesInitialized() method when
the styles for a component are first initialized. | AdvancedStyleClient | ||
Returns the string representation of this object, formatted according to locale-specific conventions. | Object | ||
Returns the string representation of the specified object. | Object | ||
Returns the primitive value of the specified object. | Object | ||
Checks whether an event listener is registered with this EventDispatcher object or any of
its ancestors for the specified event type. | EventDispatcher |
Styles are either common or associated with a specific theme. If the style is common, it can be used with any theme. If a style is associated with a specific theme, it can only be used if your application uses that theme.
SortingCollator | () | Constructor |
public function SortingCollator()
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4.5 |
Runtime Versions: | Flash Player 10.1, AIR 2.5 |
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.
