public abstract class AbstractBufferRow
extends AbstractResultsetRow

A ResultSetRow implementation that holds one row packet (which is re-used by the driver, and thus saves memory allocations), and tries when possible to avoid allocations to break out the results as individual byte[]s. (this isn't possible when doing things like reading floating point values).

rowFromServer

protected NativePacketPayload rowFromServer

homePosition

protected int homePosition

The beginning of the row packet

lastRequestedIndex

protected int lastRequestedIndex

The last-requested index, used as an optimization, if you ask for the same index, we won't seek to find it. If you ask for an index that is greater than the last one requested, we start seeking from the last requested index.

lastRequestedPos

protected int lastRequestedPos

The position of the last-requested index, optimization in concert with lastRequestedIndex.
