方法概要

修饰符和类型	方法	说明
default T	read(int maxRows, boolean streamResults, M resultPacket, ColumnDefinition metadata, ProtocolEntityFactory<T,M> protocolEntityFactory)	Reads one result set off of the wire, if the result is actually an update count, creates an update-count only result set.

方法详细资料

read

default T read(ProtocolEntityFactory<T,M> sf)
        throws IOException

参数:

sf - ProtocolEntityFactory instance

返回:

ProtocolEntity instance

抛出:

IOException - if an error occurs

read

default T read(int maxRows,
               boolean streamResults,
               M resultPacket,
               ColumnDefinition metadata,
               ProtocolEntityFactory<T,M> protocolEntityFactory)
        throws IOException

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

参数:

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

protocolEntityFactory - ProtocolEntityFactory instance

返回:

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

抛出:

IOException - if an error occurs while reading the rows
