Examples of com.persistit.Accumulator$SeqAccumulator

com.persistit.Accumulator
An Accumulator used to generate unique ID values. The {@link com.persistit.Accumulator.SeqAccumulator#allocate()} methodgenerates a new, unique long value. The transaction records this value as a candidate for maximum value of the Accumulator. On recovery, the highest such value ever allocated by a committed transaction is recovered, and so after recovery the next allocated ID value will be larger than any previously consumed.

import com.persistit.exception.PersistitInterruptedException;


public class AccumulatorAdapter {


    public static long getSnapshot(AccumInfo accumInfo, Tree tree) throws PersistitInterruptedException {
        Accumulator accumulator = getAccumulator(accumInfo, tree);
        return accumulator.getSnapshotValue();
    }
