- Method Detail
  - setDouble
```
void setDouble(int rowId,
               double value)
```
    Set double at rowId with the provided value.
  - setDoublesFromBinary
```
void setDoublesFromBinary(int rowId,
                          int count,
                          byte[] src,
                          int srcIndex)
```
    Set doubles from binary, need use UNSAFE to copy.
    
    Parameters:
    
    rowId - set start rowId.
    
    count - count for double, so the bytes size is count * 8.
    
    src - source binary.
    
    srcIndex - source binary index, it is the index for byte index.
  - fill
```
void fill(double value)
```
    Fill the column vector with the provided value.
