void	fill(int value) Fill the column vector with the provided value.
int	getInt(int i)
void	setInt(int i, 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.
void	setInts(int rowId, int count, int[] src, int srcIndex) Sets values from [src[srcIndex], src[srcIndex + count]) to [rowId, rowId + count).
void	setIntsFromBinary(int rowId, int count, byte[] src, int srcIndex) Set ints from binary, need use UNSAFE to copy.

方法详细资料

getInt

public int getInt(int i)

指定者:

getInt 在接口中 IntColumnVector

setInt

public void setInt(int i,
                   int value)

从接口复制的说明: WritableIntVector

Set int at rowId with the provided value.

指定者:

setInt 在接口中 WritableIntVector

setIntsFromBinary

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

从接口复制的说明: WritableIntVector

Set ints from binary, need use UNSAFE to copy.

指定者:

setIntsFromBinary 在接口中 WritableIntVector

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

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

从接口复制的说明: WritableIntVector

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

指定者:

setInts 在接口中 WritableIntVector

setInts

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

从接口复制的说明: WritableIntVector

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

指定者:

setInts 在接口中 WritableIntVector

fill

public void fill(int value)

从接口复制的说明: WritableIntVector

Fill the column vector with the provided value.

指定者:

fill 在接口中 WritableIntVector
