BundleLoader (Oracle Fusion Middleware Java API Reference for Oracle Extension SDK Reference)

By default the strategy for fetching resource bundles requires a large number of class and resource fetches; the method ResourceBundle.getBundle(String,Locale,ClassLoader) gives precise details. Many of these are speculative - the fetch frequently fails - and this imposes a significant overhead for any resource bundle fetch. For example, it is unusual for translations specific to American and British English to exist so there are rarely bundles suffixed with 'en_US' or 'en_GB'. In fact often 'en' does not exist as the base resource is English. For a large number of resources the set of translated locales is a given. The BundleLoader takes advantage of this knowledge to minimise speculative searches for the default locale. Setting the System property oracle.translated.locales to a comma separated list of locales, eg oracle.translated.locales=ja,fr_CA, specifies the available translations. The BundleLoader uses this list to determine which extant locale should be used as the default.

Constructor Summary
`BundleLoader(java.util.Locale locale, java.lang.String inclusionList)` Constructs a `BundleLoader` that maps `locale` to a restricted one given the `inclusionList`.

Method Summary
`static java.util.ResourceBundle`	`getBundle(java.lang.String baseName)` Deprecated. JDeveloper now has multiple classloaders and this method is thus unsafe because, unlike `ResourceBundle.getBundle(String)` it doesn't use the call stack to determine the caller.
`static java.util.ResourceBundle`	`getBundle(java.lang.String baseName, java.lang.ClassLoader loader)` Gets a resource bundle using the 'default' locale and the supplied class loader.

Constructor Detail

BundleLoader

public BundleLoader(java.util.Locale locale,
                    java.lang.String inclusionList)

Constructs a BundleLoader that maps locale to a restricted one given the inclusionList.

Parameters:: locale - locale to map, must not be null; inclusionList - comma separated list of available locales or null for no restrictions

Method Detail

getBundle

public static final java.util.ResourceBundle getBundle(java.lang.String baseName)

Deprecated. JDeveloper now has multiple classloaders and this method is thus unsafe because, unlike ResourceBundle.getBundle(String) it doesn't use the call stack to determine the caller.

Gets a resource bundle using the 'default' locale and the class loader for this class. Using the class loader for BundleLoader is an important difference from ResourceBundle which uses the class loader of the calling class.

getBundle

public static final java.util.ResourceBundle getBundle(java.lang.String baseName,
                                                       java.lang.ClassLoader loader)

Gets a resource bundle using the 'default' locale and the supplied class loader. This method should be used if the caller class was loaded by a different class loader than this class.
