Modifier and Type | Method and Description |
---|---|
Long |
add(Long l1,
Long l2)
nn * @return sum or non null value among (if either of them is null); otherwise returns a null.
|
Long |
castToCellType(Long l)
The response message comes as type S.
|
Long |
castToReturnType(Long o)
provides casting opportunity between the data types.
|
int |
compare(Long l1,
Long l2)
This takes care if either of arguments are null.
|
double |
divideForAvg(Long l1,
Long l2)
used for computing average of <S> data values.
|
Long |
getCellValueFromProto(org.apache.hadoop.hbase.protobuf.generated.HBaseProtos.LongMsg q)
This method gets the PB message corresponding to the cell type n * @return the cell-type
instance from the PB message
|
Long |
getMaxValue()
returns the maximum value for this type T n
|
Long |
getMinValue() |
Long |
getPromotedValueFromProto(org.apache.hadoop.hbase.protobuf.generated.HBaseProtos.LongMsg r)
This method gets the promoted type from the proto message n * @return the promoted-type
instance from the PB message
|
org.apache.hadoop.hbase.protobuf.generated.HBaseProtos.LongMsg |
getProtoForCellType(Long t)
This method gets the PB message corresponding to the cell type n * @return the PB message for
the cell-type instance
|
org.apache.hadoop.hbase.protobuf.generated.HBaseProtos.LongMsg |
getProtoForPromotedType(Long s)
This method gets the PB message corresponding to the promoted type n * @return the PB message
for the promoted-type instance
|
org.apache.hadoop.hbase.protobuf.generated.HBaseProtos.EmptyMsg |
getRequestData()
This method should return any additional data that is needed on the server side to construct
the ColumnInterpreter.
|
Long |
getValue(byte[] colFamily,
byte[] colQualifier,
Cell kv)
nnn * @return value of type T n
|
Long |
increment(Long o)
nn
|
void |
initialize(org.apache.hadoop.hbase.protobuf.generated.HBaseProtos.EmptyMsg msg)
This method should initialize any field(s) of the ColumnInterpreter with a parsing of the
passed message bytes (used on the server side).
