Description copied from interface: ProtocolEntityReader

Reads one result set off of the wire, if the result is actually an update count, creates an update-count only result set.

Specified by:

read in interface ProtocolEntityReader<Resultset,NativePacketPayload>

Parameters:

maxRows - the maximum number of rows to read (-1 means all rows)

streamResults - should the driver leave the results on the wire, and read them only when needed?

resultPacket - the first packet of information in the result set

metadata - use this metadata instead of the one provided on wire

resultSetFactory - ProtocolEntityFactory instance

Returns:

a result set that either represents the rows, or an update count

Throws:

java.io.IOException - if an error occurs while reading the rows
