CollatorBase is a base class for the
SortingCollator and MatchingCollator classes.
This class is a wrapper class around the
flash.globalization.Collator class.
Therefore the locale-specific string comparison is provided by the
flash.globalization.Collator class.
However by using this class as a base class, the SortingCollator
and MatchingCollator classes can be used in MXML declartions.
In these classes, the locale style is used for the
requested Locale ID name and has methods and properties that are bindable.
The flash.globalization.Collator class uses the underlying operating system for the formatting functionality and to supply locale specific data. On some operating systems, the flash.globalization classes are unsupported. On these systems the wrapper class provides fallback functionality for string comparison.

actualLocaleIDName | property |
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.

ignoreCharacterWidth | property |
ignoreCharacterWidth:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4.5 |
| Runtime Versions: | Flash Player 10.1, AIR 2.5 |
When this property is true, full-width and half-width forms of some Chinese and Japanese characters are evaluated as equal.
For compatibility with existing standards for Chinese and Japanese
character sets, Unicode provides character codes for both full-width
and half width-forms of some characters.
For example, when the ignoreCharacterWidth property is
set to true,
compare("Ａｱ", "Aア")
returns true.
If the ignoreCharacterWidth property is set to
false, then full-width and half-width forms are not
equal to one another.
The default value is true when the
CollatorBase() constructor's initialMode
parameter is set to Collator.MATCHING.
false when the CollatorBase()
constructor's initialMode parameter is set to
Collator.SORTING.

ignoreDiacritics | property |
ignoreDiacritics:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4.5 |
| Runtime Versions: | Flash Player 10.1, AIR 2.5 |
When this property is set to true, strings that use the same base
characters but different accents or other diacritic marks are
evaluated as equal.
For example compare("coté", "côte") returns
true when the ignoreDiacritics property is
set to true.
When the ignoreDiacritics is set to
false then base characters with diacritic marks or
accents are not considered equal to one another.
The default value is true when the
CollatorBase() constructor's initialMode
parameter is set to Collator.MATCHING.
false when the CollatorBase()
constructor's initialMode parameter is set to
Collator.SORTING.
This property can be used as the source for data binding. When this property is modified, it dispatches the change event.

| Product Version: | Flex 4.5 |
| Runtime Versions: | Flash Player 10.1, AIR 2.5 |
When this property is set to true, strings that differ only by the
type of kana character being used are treated as equal.
For example,
compare("カナ", "かな")
returns true when the ignoreKanaType
property is set to true.
If the ignoreKanaType is set to false
then hiragana and katakana characters that refer to the same syllable
are not equal to one another.

spaces, currency symbols, math symbols, and other types of symbols
are ignored when sorting or matching.
For example the strings "OBrian", "O'Brian", and "O Brian" would all
be treated as equal when the ignoreSymbols property is
set to true.
The default value is true when the
CollatorBase() constructor's initialMode
parameter is set to Collator.MATCHING.
false when the CollatorBase()
constructor's initialMode parameter is set to
Collator.SORTING.

numericComparison | property |
numericComparison:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4.5 |
| Runtime Versions: | Flash Player 10.1, AIR 2.5 |
Controls how numeric values embedded in strings are handled during string comparison.
When the numericComparison property is set to
true, the compare method converts numbers that appear in
strings to numerical values for comparison.
When this property is set to false, the comparison
treats numbers as character codes and sort them according to the
rules for sorting characters in the specified locale.
For example, when this property is true for the locale ID "en-US", then the strings "version1", "version10", and "version2" are sorted into the following order: version1 < version2 < version10.
When this property is false for "en-US", those same strings are sorted into the following order: version1 < version10 < version2.
The default value is false.
This property can be used as the source for data binding. When this property is modified, it dispatches the change event.

CollatorBase | () | Constructor |
public function CollatorBase(initialMode:String)| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4.5 |
| Runtime Versions: | Flash Player 10.1, AIR 2.5 |
Constructs a new CollatorBase object to provide string comparisons according to the conventions of a specified locale.
The initialMode parameter sets the initial collation
options for two use cases: sorting and matching.
It can be set to one of the two following values:
CollatorMode.SORTING: sets the collation options for general linguistic sorting uses 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.CollatorMode.MATCHING: sets collation options for uses such as determining if two strings are equivalent. In this mode, differences in uppercase and lower case letters, accented characters, and so on are ignored when doing string comparisons.
For more details and examples of using these two modes, 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
UIComponentby calling the UIComponent'saddStyleClientmethod with an instance of this object as the parameter. - By using the class in an MXML declaration and inheriting the
localestyle from the document that contains the declaration.<fx:Declarations> <s:SortingCollator id="collator" /> </fx:Declarations> - By using an MXML declaration and specifying the
localevalue in the list of assignments.<fx:Declarations> <s:SortingCollator id="collator_german" locale="de-DE" /> </fx:Declarations> - Calling the setStyle method, e.g.
collator.setStyle("locale", "de-DE")
If the locale style is not set by one of the above
techniques, the
methods of this class that depend on the locale set the
lastOperationStatus property to
spark.globalization.LastOperationStatus.LOCALE_UNDEFINED_ERROR.
initialMode:String — Sets the initial collation options for two use
cases: sorting and matching.
