There are three main concepts involved in localization: locales, resources, and resource bundles.
A locale specifies a language and a country
for which your application has been localized.
For example, the locale "en_US"
specifies English as spoken in the United States.
(See the mx.resources.Locale class for more information.)
A resource is a named value that is locale-dependent.
For example, your application might have a resource
whose name is "OPEN"
and whose value for an English locale is "Open"
but whose value for a French locale is "Ouvrir".
A resource bundle is a named group of resources
whose values have been localized for a particular locale.
A resource bundle is identified by the combination of its
bundleName and its locale,
and has a content object that contains
the name-value pairs for the bundle's resources.
See the documentation for mx.resources.IResourceBundle
for information about how you typically create resource
bundles from properties files.
A single ResourceManager object implementing the IResourceManager
interface manages multiple resource bundles, possibly for multiple
locales, and provides access to the resources that they contain.
For example, you can retrieve a specific resource as a String by calling
resourceManager.getString(bundleName, resourceName).
All classes that extend UIComponent, Formatter, or Validator
have a resourceManager property
that provides a reference to the object implementing this interface.
Other classes can call ResourceManager.getInstance()
to obtain this object.
Resource retrieval methods such as getString()
search for resources in the locales specified
by the localeChain property.
By changing this property, you can make your application
suddenly use, for example, Japanese rather than English resources.
When your application starts, the ResourceManager is automatically populated with whatever resource bundles were compiled into the application. If you create a code module, by default the resources that its classes need are compiled into the module. When the module is loaded into an application, any bundles that the application does not already have are added to the ResourceManager.
You can compile "resource modules" which have only resources in them,
and load them with the loadResourceModule() method
of IResourceManager.
With resource modules, you can support multiple locales by loading
the resources you need at run time rather than compiling them into
your application.
Although the ResourceManager is normally populated with resource bundles
that were compiled into your application or loaded from modules,
you can also programmatically create resource bundles and add them
to the ResourceManager yourself with the addResourceBundle()
method.

localeChain | proprietà |
localeChain:Array| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
An Array of locale Strings, such as [ "en_US" ],
which specifies one or more locales to be searched for resources.
When you call the ResourceManager methods getObject(),
getString(), getStringArray(),
getNumber(), getInt(),
getUint(), getBoolean(), or
getClass() to get the value of a resource,
you specify a bundle name and a resource name,
but not a locale.
The ResourceManager starts with the first locale in the
localeChain and looks for a ResourceBundle
with the specified bundle name for that locale.
If such a ResourceBundle exists, and the specified resource
exists in it, then the value of that resource is returned.
Otherwise, the ResourceManager proceeds on to the other
locales in the localeChain.
This scheme makes it possible to have locales that do not
necessarily contain a complete set of localized resources.
For example, if you are localizing your application for
Indian English rather than U.S. English, you need only
supply resources for the en_IN locale in which the
Indian spelling or usage differs from that in the U.S.,
and then set the localeChain property
to [ "en_IN", "en_US" ].
Many framework classes assume that they can always
obtain, from some locale, the resources that they expect,
and they will throw errors if they cannot do so.
Therefore, you must ensure that the localeChain
always contains a complete set of resources.
Unless you have done a complete localization of all the
framework's resources as well as your own application's
resources, you can keep the "en_US" locale
at the end of your localeChain to ensure this.
Setting this property causes the ResourceManager to dispatch
a "change" Event.
