Example 1 with FSLockFactory

use of org.apache.lucene.store.FSLockFactory in project lucene-solr by apache.

the class LuceneTestCase method newDirectoryImpl.

static Directory newDirectoryImpl(Random random, String clazzName, LockFactory lf) {
    if (clazzName.equals("random")) {
        if (rarely(random)) {
            clazzName = RandomPicks.randomFrom(random, CORE_DIRECTORIES);

            clazzName = "RAMDirectory";
        }
    }
    try {
        final Class<? extends Directory> clazz = CommandLineUtil.loadDirectoryClass(clazzName);
        // If it is a FSDirectory type, try its ctor(Path)
        if (FSDirectory.class.isAssignableFrom(clazz)) {

        } catch (NoSuchMethodException nsme) {
        // Ignore
        }
        // the remaining dirs are no longer filesystem based, so we must check that the passedLockFactory is not file based:
