Examples with LogService org.osgi.service.log.LogService used on opensource projects

Example 51 with LogService

use of org.osgi.service.log.LogService in project eclipse.platform.runtime by eclipse.

the class ResourceBundleHelper method toLocale.

/**
 * <p>
 * Converts a String to a Locale.
 * </p>
 *
 * <p>
 * This method takes the string format of a locale and creates the locale object from it.
 * </p>
 *
 * <pre>
 *   MessageFactoryServiceImpl.toLocale("en")         = new Locale("en", "")
 *   MessageFactoryServiceImpl.toLocale("en_GB")      = new Locale("en", "GB")
 *   MessageFactoryServiceImpl.toLocale("en_GB_xxx")  = new Locale("en", "GB", "xxx")
 * </pre>
 *
 * <p>
 * This method validates the input strictly. The language code must be lowercase. The country
 * code must be uppercase. The separator must be an underscore. The length must be correct.
 * </p>
 *
 * <p>
 * This method is inspired by <code>org.apache.commons.lang.LocaleUtils.toLocale(String)</code>
 * by fixing the parsing error for uncommon Locales like having a language and a variant code
 * but no country code, or a Locale that only consists of a country code.
 * </p>
 *
 * <p>
 * <b>Note:</b> This is the same logic as used in <code>EquinoxConfiguration.toLocale()</code>
 * </p>
 *
 * @param localeString
 *            the locale String to convert
 * @param defaultLocale
 *            the Locale that should be returned in case of an invalid Locale String
 * @return a Locale that matches the specified locale String. If the given input String is
 *         <code>null</code> or can not be parsed because of an invalid format, the given
 *         default {@link Locale} will be returned.
