From source file:uk.ac.bbsrc.tgac.miso.tools.run.FileQueueMessageSource.java

public Message<Set<File>> receive() throws MessagingException {
    Message<Set<File>> message = null;

    // rescan only if needed or explicitly configured
    if (scanEachPoll || toBeReceived.isEmpty()) {
        scanInputDirectory();/*from w  w  w  . j  a  v  a 2s  .  c om*/
    }

    //instead of doing a poll() for a single files, drain the whole queue into a set
    Set<File> files = new HashSet<File>();
    toBeReceived.drainTo(files);

    for (File file : files) {
        while ((file != null) && !scanner.tryClaim(file)) {
