Usage

From source file:ch.algotrader.service.HistoricalDataServiceImpl.java

private void updateBars(final long securityId, final Duration barSize, List<Bar> bars) {

    // get the last Bar int the Database
    final Bar lastBar = CollectionUtil
            .getSingleElementOrNull(this.barDao.findBarsBySecurityAndBarSize(1, securityId, barSize));

    // remove all Bars prior to the lastBar
    if (lastBar != null) {

        CollectionUtils.filter(bars, new Predicate<Bar>() {
            @Override/*w w w. j  a  v  a2 s. co  m*/
            public boolean evaluate(Bar bar) {
                return bar.getDateTime().compareTo(lastBar.getDateTime()) > 0;
            }
        });
    }

    // save the Bars
    this.barDao.saveAll(bars);

    if (LOGGER.isInfoEnabled()) {
        LOGGER.info("created {} new bars for security {}", bars.size(), securityId);
