Examples of com.sematext.hbase.hut.ByteArrayWrapper

com.sematext.hbase.hut.ByteArrayWrapper
Byte array wrapper. It can be used as a HashMap key. It is assumed that array is never changes. (Yep, we could copy array in constructor to enforce that, we just don't want to use redundant space) TODO: isn't there some existing class for that?

  public SumColumnsUp(Pair<byte[], byte[]>... columns) {
    Collection<Pair<ByteArrayWrapper, ByteArrayWrapper>> cols =
            new ArrayList<Pair<ByteArrayWrapper, ByteArrayWrapper>>(columns.length);
    for (Pair<byte[], byte[]> column : columns) {
      cols.add(new Pair<ByteArrayWrapper, ByteArrayWrapper>(
              new ByteArrayWrapper(column.getFirst()), new ByteArrayWrapper(column.getSecond())));
    }
    this.columns = cols;
