the describe of KeyValue:

...

• HBase applications and users should use the Cell interface and avoid directly using KeyValue and
• member functions not defined in Cell.
  ...

for example,the use case of ColumnRangeFilter:

...
ResultScanner rs = t.getScanner(scan);
for (Result r = rs.next(); r != null; r = rs.next()) {
for (KeyValue kv : r.raw())

{ // each kv represents a column }

}
