Method Detail

readReusablePacket

com.singlestore.jdbc.client.ReadableByteBuf readReusablePacket(boolean traceEnable)
                                                        throws IOException

Get next MySQL packet. Packet is expected to have size < 16M and will use if possible an internal cached buffer. This packet bytes are expect to be read immediately

Parameters:

traceEnable - must trace packet

Returns:

Readable byte array packet.

Throws:

IOException - if socket exception occur.

readReusablePacket

com.singlestore.jdbc.client.ReadableByteBuf readReusablePacket()
                                                        throws IOException

Get next MySQL packet. Packet is expected to have size < 16M and will use if possible an internal cached buffer. This packet bytes are expect to be read immediately

Returns:

Readable byte array packet.

Throws:

IOException - if socket exception occur.

readPacket

byte[] readPacket(boolean traceEnable)
           throws IOException

Get next MySQL packet. If packet is more than 16M, read as many packet needed to finish reading MySQL packet. (first that has not length = 16Mb)

Parameters:

traceEnable - must trace packet.

Returns:

array packet.

Throws:

IOException - if socket exception occur.

readableBufFromArray

com.singlestore.jdbc.client.ReadableByteBuf readableBufFromArray(byte[] buf)

Get a readable byte array from byte array. This packet is expected to be read immediately, since no lock is set on this packet.

Parameters:

buf - byte array to be parsed

Returns:

array packet.

skipPacket

void skipPacket()
         throws IOException

Skip next MySQL packet. Packet is expected to have size < 16M

Throws:

IOException - if socket exception occur.

getSequence

MutableByte getSequence()

Get current sequence object

Returns:

current sequence

close

void close()
    throws IOException

Close stream

Throws:

IOException - if any error occurs

setServerThreadId

void setServerThreadId(Long serverThreadId,
                       HostAddress hostAddress)

Set server thread id.

Parameters:

serverThreadId - current server thread id.

hostAddress - host information
