`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

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.

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

Implementation
`public function get actualLocaleIDName():String`

flash.globalization.Collator.actualLocaleIDName
CollatorBase()

ignoreCase | property |

`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.

Implementation
`public function get ignoreCase():Boolean`
`public function set ignoreCase(value:Boolean):void`

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`.

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

Implementation
`public function get ignoreCharacterWidth():Boolean`
`public function set ignoreCharacterWidth(value:Boolean):void`

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.

Implementation
`public function get ignoreDiacritics():Boolean`
`public function set ignoreDiacritics(value:Boolean):void`

ignoreKanaType | property |

`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.

Implementation
`public function get ignoreKanaType():Boolean`
`public function set ignoreKanaType(value:Boolean):void`

ignoreSymbols | property |

`ignoreSymbols: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 is true, symbol characters such as 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`.

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

Implementation
`public function get ignoreSymbols():Boolean`
`public function set ignoreSymbols(value:Boolean):void`

lastOperationStatus | property |

`lastOperationStatus:String` [read-only] [override]

Language Version : | ActionScript 3.0

Product Version : | Flex 4.5

Runtime Versions : | Flash Player 10.1, AIR 2.5

The status of the most recent operation that this class object performed. The `lastOperationStatus` is set whenever the constructor or a method of this class is called, or when a property is set. For the possible values see the description under each method.

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

Implementation
`public function get lastOperationStatus():String`

See also

spark.globalization.LastOperationStatus

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.

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:

- `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 `UIComponent` by calling the UIComponent's `addStyleClient` method with an instance of this object as the parameter.
- By using the class in an MXML declaration and inheriting the `locale` style from the document that contains the declaration.

                <fx:Declarations>
                       <s:SortingCollator id="collator" />
                </fx:Declarations>

- By using an MXML declaration and specifying the `locale` value 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`.

Parameters

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

Method Detail

compare | () | method

`public function compare(string1:String, string2:String):int`

Language Version : | ActionScript 3.0

Product Version : | Flex 4.5

Runtime Versions : | Flash Player 10.1, AIR 2.5

Compares two strings and returns an integer value indicating whether the first string is less than, equal to, or greater than the second string. The comparison uses the sort order rules for the `locale` sytle that is in effect when the compare method is called.

Parameters

| `string1:String` — First comparison string.
| `string2:String` — Second comparison string.

Returns

| `int` — An integer value indicating whether the first string is less than, equal to, or greater than the second string. If the return value is negative, `string1` is less than `string2` or `string2` is `null`. If the return value is zero, `string1` is equal to `string2`. If the return value is positive, `string1` is larger than `string2` or `string1` is `null`.
