Examples with InvalidEnvelopedEntryException org.apache.distributedlog.exceptions.InvalidEnvelopedEntryException used on opensource projects

Example 1 with InvalidEnvelopedEntryException

use of org.apache.distributedlog.exceptions.InvalidEnvelopedEntryException in project bookkeeper by apache.

the class BKLogSegmentWriter method flushIfNeeded.

// Based on transmit buffer size, immediate flush, etc., should we flush the current
// packet now.

    if (outstandingBytes > transmissionThreshold) {
        // If flush delay is disabled, flush immediately, else schedule appropriately.

            checkStateAndTransmit();

                }
            }, transmitSchedFutureRefUpdater);
            // Timing here is not very important--the last flush failed and we should
            // indicate this to the caller. The next flush may succeed and unset the
            // scheduledFlushException in which case the next write will succeed (if the caller
            // hasn't already closed the writer).
            Exception exec = scheduledFlushExceptionUpdater.get(this);

Example 2 with InvalidEnvelopedEntryException

use of org.apache.distributedlog.exceptions.InvalidEnvelopedEntryException in project bookkeeper by apache.

the class BKLogSegmentWriter method transmit.

/**
 * Transmit the current buffer to bookkeeper.
 * Synchronised at the class. #write() and #flush()
 * are never called at the same time.
 * NOTE: This method should only throw known exceptions so that we don't accidentally
 *       add new code that throws in an inappropriate place.
 *
 * @return a transmit future for caller to wait for transmit result if we transmit successfully,
 *         null if no data to transmit
 * @throws BKTransmitException if the segment writer is already in error state
 * @throws LockingException if the segment writer lost lock before transmit
 * @throws WriteException if failed to create the envelope for the data to transmit
 * @throws InvalidEnvelopedEntryException when built an invalid enveloped entry
