Usage

From source file:net.sourceforge.pmd.lang.LanguageRegistry.java

private LanguageRegistry() {
    List<Language> languagesList = new ArrayList<>();
    // Use current class' classloader instead of the threads context classloader, see https://github.com/pmd/pmd/issues/1377
    ServiceLoader<Language> languageLoader = ServiceLoader.load(Language.class, getClass().getClassLoader());
    Iterator<Language> iterator = languageLoader.iterator();
    while (iterator.hasNext()) {
        try {/*from   w  w  w . j ava  2  s  . co  m*/
            Language language = iterator.next();
            languagesList.add(language);
        } catch (UnsupportedClassVersionError e) {
            // Some languages require java8 and are therefore only available
            // if java8 or later is used as runtime.
            System.err.println("Ignoring language for PMD: " + e.toString());
        }
    }

    // sort languages by terse name. Avoiding differences in the order of languages
    // across JVM versions / OS.
    Collections.sort(languagesList, new Comparator<Language>() {
        @Override
        public int compare(Language o1, Language o2) {
            return o1.getTerseName().compareToIgnoreCase(o2.getTerseName());
        }
    });

    // using a linked hash map to maintain insertion order
    languages = new LinkedHashMap<>();
    for (Language language : languagesList) {
        languages.put(language.getName(), language);
    }
}
