Modifier and Type | Method and Description |
---|---|
Double |
add(Double d1,
Double d2)
nn * @return sum or non null value among (if either of them is null); otherwise returns a null.
|
Double |
castToCellType(Double d)
The response message comes as type S.
|
Double |
castToReturnType(Double o)
provides casting opportunity between the data types.
|
int |
compare(Double d1,
Double d2)
This takes care if either of arguments are null.
|
double |
divideForAvg(Double d1,
Long l2)
used for computing average of <S> data values.
|
Double |
getCellValueFromProto(org.apache.hadoop.hbase.protobuf.generated.HBaseProtos.DoubleMsg q)
This method gets the PB message corresponding to the cell type n * @return the cell-type
instance from the PB message
|
Double |
getMaxValue()
returns the maximum value for this type T n
|
Double |
getMinValue() |
Double |
getPromotedValueFromProto(org.apache.hadoop.hbase.protobuf.generated.HBaseProtos.DoubleMsg 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.DoubleMsg |
getProtoForCellType(Double 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.DoubleMsg |
getProtoForPromotedType(Double 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.

Double |
getValue(byte[] colFamily,
byte[] colQualifier,
Cell c)
nnn * @return value of type T n
|
Double |
increment(Double 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).
