Method Detail

setFloat

void setFloat(int rowId,
              float value)

Set float at rowId with the provided value.

setFloatsFromBinary

void setFloatsFromBinary(int rowId,
                         int count,
                         byte[] src,
                         int srcIndex)

Set floats from binary, need use UNSAFE to copy.

Parameters:

rowId - set start rowId.

count - count for float, so the bytes size is count * 4.

src - source binary.

srcIndex - source binary index, it is the index for byte index.

fill

void fill(float value)

Fill the column vector with the provided value.
