func

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

TRIM element i of the vector, eliminating blanks from the left and right sides of the string, 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.
