Imports
com.mysql.cj.exceptions.ExceptionInterceptor, com.mysql.cj.protocol.a.NativePacketPayload, com.mysql.cj.protocol.result.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).

Field Summary

Modifier and TypeField and Description
protected int
homePosition

The beginning of the row packet

lastRequestedIndex

The last-requested index, used as an optimization, if you ask for the same index, we won't seek to find it.

protected int
lastRequestedPos

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