Class BundleLoader

java.lang.Object

oracle.javatools.util.BundleLoader

Deprecated.

As of JDEVADF 12.1.3.0.0. Use java.util.ResourceBundle instead and call one of its getBundle methods that take a ResourceBundle.Control as argument and pass an instance of TranslationControl to them.

public class BundleLoader
extends java.lang.Object

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. TODO: This class ought to be replaced by an equivalent ResourceBundle.Control, which offers scope for improved performance by eliminating .properties lookups. In theory it also ought to be possible to create an index of real available resources, allowing different strategies to be used for different basenames.
