方法详细资料

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.

参数:

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.
