方法概要

限定符和类型	方法和说明
void	fill(int value) Fill the column vector with the provided value.
void	setInt(int rowId, int value) Set int at rowId with the provided value.
void	setInts(int rowId, int count, int value) Sets value to [rowId, rowId + count) by the value, this is data that repeats continuously.

方法详细资料

setInt

void setInt(int rowId,
            int value)

Set int at rowId with the provided value.

setIntsFromBinary

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

Set ints from binary, need use UNSAFE to copy.

参数:

rowId - set start rowId.

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

src - source binary.

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

setInts

void setInts(int rowId,
             int count,
             int value)

Sets value to [rowId, rowId + count) by the value, this is data that repeats continuously.

setInts

void setInts(int rowId,
             int count,
             int[] src,
             int srcIndex)

Sets values from [src[srcIndex], src[srcIndex + count]) to [rowId, rowId + count).

fill

void fill(int value)

Fill the column vector with the provided value.
