Method Details

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.
