Method Details

getChunkId

public int getChunkId()

Description copied from interface: ExtendedCell

Extracts the id of the backing bytebuffer of this cell if it was obtained from fixed sized chunks as in case of MemstoreLAB

Returns:

the chunk id if the cell is backed by fixed sized Chunks, else return ExtendedCell.CELL_NOT_BASED_ON_CHUNK; i.e. -1.
