Example 11 with CloseableIterator

use of co.cask.cdap.api.dataset.lib.CloseableIterator in project cdap by caskdata.

the class MockLogReader method getLog.

@Override

    CollectingCallback collectingCallback = new CollectingCallback();
    // since its just for test case, we don't need to lazily read logs (which is the purpose of returning an Iterator)
    long fromOffset = getOffset(fromTimeMs / 1000);
    long toOffset = getOffset(toTimeMs / 1000);
    getLogNext(loggingContext, new ReadRange(fromTimeMs, toTimeMs, fromOffset), (int) (toOffset - fromOffset), filter, collectingCallback);
    final Iterator<LogEvent> iterator = collectingCallback.getLogEvents().iterator();
    return new CloseableIterator<LogEvent>() {

        @Override
        public boolean hasNext() {
            return iterator.hasNext();
        }
