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.

Property Detail
actualLocaleIDNameproperty
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.

This property can be used as the source for data binding.

ignoreCase: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, identical strings and strings that differ only in the case of the letters are evaluated as equal.

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.

ignoreCharacterWidthproperty 
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.

This property can be used as the source for data binding.


Implementation
    public function get ignoreCharacterWidth():Boolean

ignoreDiacriticsproperty 
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.


Implementation

ignoreKanaTypeproperty 
ignoreKanaType: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 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.

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.

numericComparisonproperty 
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.


Implementation
    public function get numericComparison():Boolean
    public function set numericComparison(value:Boolean):void

Constructor Detail
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:

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:

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.

Parameters
initialMode:String — Sets the initial collation options for two use cases: sorting and matching.
