Examples of org.apache.hadoop.hbase.TagRewriteCell

org.apache.hadoop.hbase.TagRewriteCell
This can be used when a Cell has to change with addition/removal of one or more tags. This is an efficient way to do so in which only the tags bytes part need to recreated and copied. All other parts, refer to the original Cell.

            cell.getTagsOffset(), cell.getTagsLength());
          while (tagIterator.hasNext()) {
            tags.add(tagIterator.next());
          }
        }
        newCells.add(new TagRewriteCell(cell, Tag.fromList(tags)));
      }
      // This is supposed to be safe, won't CME
      e.setValue(newCells);
    }
  }

    // If we have no tags to add, just return
    if (tags.isEmpty()) {
      return newCell;
    }


    Cell rewriteCell = new TagRewriteCell(newCell, Tag.fromList(tags));
    return rewriteCell;
  }
