public static ResourceBundle getBundle(String baseName, Locale locale, ClassLoader loader)
Conceptually, getBundle uses the following strategy for locating and instantiating
resource bundles:
getBundle uses the base name, the specified locale, and the default
locale (obtained from Locale.getDefault)
to generate a sequence of candidate bundle names.
If the specified locale's language, country, and variant are all empty
strings, then the base name is the only candidate bundle name.
Otherwise, the following sequence is generated from the attribute
values of the specified locale (language1, country1, and variant1)
and of the default locale (language2, country2, and variant2):
Candidate bundle names where the final component is an empty string are omitted. For example, if country1 is an empty string, the second candidate bundle name is omitted.
getBundle then iterates over the candidate bundle names to find the first
one for which it can instantiate an actual resource bundle. For each candidate
bundle name, it attempts to create a resource bundle:
getBundle creates a new instance of this class and uses it as the result
resource bundle.
getBundle attempts to locate a property resource file.
It generates a path name from the candidate bundle name by replacing all "." characters
with "/" and appending the string ".properties".
It attempts to find a "resource" with this name using
ClassLoader.getResource.
(Note that a "resource" in the sense of getResource has nothing to do with
the contents of a resource bundle, it is just a container of data, such as a file.)
If it finds a "resource", it attempts to create a new
PropertyResourceBundle instance from its contents.
If successful, this instance becomes the result resource bundle.
If no result resource bundle has been found, a MissingResourceException
is thrown.
Once a result resource bundle has been found, its parent chain is instantiated.
getBundle iterates over the candidate bundle names that can be
obtained by successively removing variant, country, and language
(each time with the preceding "_") from the bundle name of the result resource bundle.
As above, candidate bundle names where the final component is an empty string are omitted.
With each of the candidate bundle names it attempts to instantiate a resource bundle, as
described above.
Whenever it succeeds, it calls the previously instantiated resource
bundle's setParent method
with the new resource bundle, unless the previously instantiated resource
bundle already has a non-null parent.
Implementations of getBundle may cache instantiated resource bundles
and return the same resource bundle instance multiple times. They may also
vary the sequence in which resource bundles are instantiated as long as the
selection of the result resource bundle and its parent chain are compatible with
the description above.
The baseName argument should be a fully qualified class name. However, for
compatibility with earlier versions, Sun's Java 2 runtime environments do not verify this,
and so it is possible to access PropertyResourceBundles by specifying a
path name (using "/") instead of a fully qualified class name (using ".").
Example: The following class and property files are provided:
MyResources.class, MyResources_fr_CH.properties, MyResources_fr_CH.class,
MyResources_fr.properties, MyResources_en.properties, MyResources_es_ES.class.
The contents of all files are valid (that is, public non-abstract subclasses of ResourceBundle for
the ".class" files, syntactically correct ".properties" files).
The default locale is Locale("en", "UK").
Calling getBundle with the shown locale argument values instantiates
resource bundles from the following sources:
baseName - the base name of the resource bundle, a fully qualified class namelocale - the locale for which a resource bundle is desiredloader - the class loader from which to load the resource bundle
private static ResourceBundle getBundleImpl(String baseName, Locale locale, ClassLoader loader)
private static Object propagate(ClassLoader loader, Vector names, Vector bundlesFound, Locale defaultLocale, Object parent)
loader - the class loader for the bundlesnames - the names of the bundles along search pathbundlesFound - the bundles corresponding to the names (some may be null)defaultLocale - the default locale at the time getBundle was calledparent - the parent of the first bundle in the path (the root bundle)
