Method Detail

func

protected void func(BytesColumnVector outV,
                    byte[][] vector,
                    int[] start,
                    int[] length,
                    int i)

LTRIM element i of the vector, and place the result in outV. Operate on the data in place, and set the output by reference to improve performance. Ignore null handling. That will be handled separately.
