Method Summary

Modifier and Type	Method and Description
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.

HeapIntVector

public HeapIntVector(int len)

Don't use this except for testing purposes.

Parameters:

len - the number of rows

Method Detail

getInt

public int getInt(int i)

Specified by:

getInt in interface IntColumnVector

setInt

public void setInt(int i,
                   int value)

Description copied from interface: WritableIntVector

Set int at rowId with the provided value.

Specified by:

setInt in interface WritableIntVector

setIntsFromBinary

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

Description copied from interface: WritableIntVector

Set ints from binary, need use UNSAFE to copy.

Specified by:

setIntsFromBinary in interface WritableIntVector

Parameters:

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)

Description copied from interface: WritableIntVector

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

Specified by:

setInts in interface WritableIntVector

setInts

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

Description copied from interface: WritableIntVector

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

Specified by:

setInts in interface WritableIntVector

fill

public void fill(int value)

Description copied from interface: WritableIntVector

Fill the column vector with the provided value.

Specified by:

fill in interface WritableIntVector
