Method Detail

parse

public static OkPacket parse(ReadableByteBuf buf,
                             Context context)
                      throws java.sql.SQLException

Parser

Parameters:

buf - packet buffer

context - connection context

Throws:

java.sql.SQLException

parseWithInfo

public static OkPacket parseWithInfo(ReadableByteBuf buf,
                                     Context context)
                              throws java.sql.SQLException

Parser, keeping the info field

Parameters:

buf - packet buffer

context - connection context

Returns:

Ok_Packet object

Throws:

java.sql.SQLException

parseSessionState

private static void parseSessionState(ReadableByteBuf buf,
                                      Context context)
                               throws java.sql.SQLException

Apply the session-state blocks following the info field. Lengths inside the blocks are server-declared: a malformed entry means nothing after it can be trusted, so the rest of the session state is ignored rather than read past its block.

Parameters:

buf - packet buffer, positioned after the info field

context - connection context

Throws:

java.sql.SQLException

getAffectedRows

public long getAffectedRows()

get affected rows

Returns:

affected rows

getLastInsertId

public long getLastInsertId()

Get last auto generated insert id

Returns:

last insert id

getInfo

public byte[] getInfo()

Get ok packet info byte array. That is usually a string value, but for first Ok_Packet, containing fingerprint info.

Returns:

info
