final class UnsafeRowWriter extends UnsafeWriter

A helper class to write data into global row buffer using UnsafeRow format.

It will remember the offset of row buffer which it starts to write, and move the cursor of row buffer while writing. If new data(can be the input record if this is the outermost writer, or nested struct if this is an inner writer) comes, the starting cursor of row buffer may be changed, so we need to call UnsafeRowWriter.resetRowWriter before writing, to update the startingOffset and clear out null bits.

Note that if this is the outermost writer, which means we will always write from the very beginning of the global row buffer, we don't need to update startingOffset and can just call zeroOutNullBytes before writing new data.
