Class | public final class StringTools |
Inheritance | StringTools Object |
Language version: | ActionScript 3.0 |
Runtime version: | AIR 2 |
In some situations the conversion between uppercase and lowercase letters is not a simple mapping from one character to another and instead requires language- or context-specific processing. For example:
The toLowerCase()
and toUpperCase()
methods of this
class provide this special case conversion logic.
Due to the use of the user's settings, the use of case conversion rules provided by the operating system, and the use of a fallback locale when a requested locale is not supported, different users can see different case conversion results even when using the same locale ID.

actualLocaleIDName | property |
actualLocaleIDName:String
[read-only]
Language version: | ActionScript 3.0 |
Runtime version: | AIR 2 |
The name of the actual locale ID used by this StringTools object.
There are three possibilities for the value of the name, depending on operating system and the
value of the requestedLocaleIDName
parameter passed to the StringTools()
constructor.
LocaleID.DEFAULT
and
the operating system provides support for the requested locale,
then the name returned is the same as the requestedLocaleIDName
property.
LocaleID.DEFAULT
was used as the value for the requestedLocaleIDName
parameter to the constructor, then the name of the current locale specified by the user's operating system is
used. The LocaleID.DEFAULT
value preserves user's customized setting in the OS.
Passing an explicit value as the requestedLocaleIDName
parameter does not necessarily give the
same result as using the LocaleID.DEFAULT
even if the two locale ID names are the same.
The user could have customized the locale settings on the machine, and by requesting an
explicit locale ID name rather than using LocaleID.DEFAULT
your application would not
retrieve those customized settings.
For example:
var tools:StringTools = new StringTools(LocaleID.DEFAULT); var aliName:String = tools.actualLocaleIDName;In the above example,
aliName
is the name of the locale corresponding to the user's current operating systems settings (e.g. "it-IT" if the user's locale is set to Italian-Italy), and not"i-default"
(the name of theLocaleID.DEFAULT
locale).
requestedLocaleIDName
specified in the constructor
then a fallback locale ID name is provided.
For Example:
var tools:StringTools = new StringTools("fr-CA"); var aliName:String = tools.actualLocaleIDName;Assuming that the operating system in the example above does not support the "fr-CA" (French-Canada) locale ID, a fallback is used. In this case the fallback locale ID is "fr-FR" (French-France).
public function get actualLocaleIDName():String

lastOperationStatus | property |
lastOperationStatus:String
[read-only]
Language version: | ActionScript 3.0 |
Runtime version: | AIR 2 |
The status of the most recent operation that this StringTools object performed.
The lastOperationStatus
property is set whenever the constructor or a method of
this class is called or another property is set. For the possible values see the description for each method.
public function get lastOperationStatus():String
See also
requestedLocaleIDName | property |
requestedLocaleIDName:String
[read-only]
Language version: | ActionScript 3.0 |
Runtime version: | AIR 2 |
The name of the requested locale ID that was passed to the constructor of this StringTools object.
If the LocaleID.DEFAULT
value was used then the name returned is "i-default".
The actual locale used can differ from the requested locale when a fallback locale is applied.
The name of the actual locale can be retrieved using the actualLocaleIDName
property.
public function get requestedLocaleIDName():String

StringTools | () | constructor |
public function StringTools(requestedLocaleIDName:String)
Language version: | ActionScript 3.0 |
Runtime version: | AIR 2 |
Constructs a new StringTools object that provides case conversion and other utilities according to the conventions of a given locale.
This constructor determines if the current operating system supports the requested locale ID name.
If it is not supported then a fallback locale is used instead.
If a fallback locale is used then the lastOperationStatus
property
indicates the type of fallback, and the actualLocaleIDName
property contains
the name of the fallback locale ID.
When this constructor completes successfully the lastOperationStatus
property is set to:
LastOperationStatus.NO_ERROR
When the requested locale ID name is not available then the lastOperationStatus
is set to one of the following:
LastOperationStatus.USING_FALLBACK_WARNING
LastOperationStatus.USING_DEFAULT_WARNING
Otherwise the lastOperationStatus
property is set to one of the constants defined in
the LastOperationStatus class.
requestedLocaleIDName:String — The preferred locale ID name to use when determining date or time formats.
|
ArgumentError — when the requestedLocaleIDName parameter is null
|

getAvailableLocaleIDNames | () | method |
public static function getAvailableLocaleIDNames():Vector.<String>
Language version: | ActionScript 3.0 |
Runtime version: | AIR 2 |
Lists all of the locale ID names supported by this class.
If this class is not supported on the current operating system, this method returns a null value.
When this method is called and it completes successfully, the lastOperationStatus
property is set to:
LastOperationStatus.NO_ERROR
Otherwise the lastOperationStatus
property is set to one of the constants defined in the
LastOperationStatus
class.
Vector.<String> — A vector of strings containing all of the locale ID names supported by this class.
|
toLowerCase | () | method |
public function toLowerCase(s:String):String
Language version: | ActionScript 3.0 |
Runtime version: | AIR 2 |
Converts a string to lowercase according to language conventions. Depending on the locale, the output string length can differ from the input string length.
When this method is called and it completes successfully, the lastOperationStatus
property is set to:
LastOperationStatus.NO_ERROR
Otherwise the lastOperationStatus
property is set to one of the constants defined in the
LastOperationStatus
class.
s:String — string to convert to lowercase.
|
String —
The converted lowercase string.
|
ArgumentError — when the s parameter is null.
|

toUpperCase | () | method |
public function toUpperCase(s:String):String
Language version: | ActionScript 3.0 |
Runtime version: | AIR 2 |
Converts a string to uppercase according to language conventions. Depending on the locale, the output string length can differ from the input string length.
When this method is called and it completes successfully, the lastOperationStatus
property is set to:
LastOperationStatus.NO_ERROR
Otherwise the lastOperationStatus
property is set to one of the constants defined in the
LastOperationStatus
class.
s:String — string to convert to uppercase.
|
String —
The converted uppercase string.
