参数类型为CellComparator的org.apache.hadoop.hbase中的方法

限定符和类型	方法和说明
static int	PrivateCellUtil.compare(CellComparator comparator, Cell left, byte[] key, int offset, int length) Used when a cell needs to be compared with a key byte[] such as cases of finding the index from the index block, bloom keys from the bloom blocks This byte[] is expected to be serialized in the KeyValue serialization format If the KeyValue (Cell's) serialization format changes this method cannot be used.
static int	CellUtil.compare(CellComparator comparator, Cell left, byte[] key, int offset, int length) 已过时。 As of HBase-2.0. Will be removed in HBase-3.0
static int	PrivateCellUtil.compareKeyBasedOnColHint(CellComparator comparator, Cell nextIndexedCell, Cell currentCell, int foff, int flen, byte[] colHint, int coff, int clen, long ts, byte type) Used to compare two cells based on the column hint provided.
static int	PrivateCellUtil.compareKeyIgnoresMvcc(CellComparator comparator, Cell left, Cell right) Compares only the key portion of a cell.
