Method Detail

getPacket

public Buffer getPacket(boolean reUsable)
                 throws IOException

Specified by:

getPacket in interface PacketInputStream

Overrides:

getPacket in class StandardPacketInputStream

Throws:

IOException

getPacketArray

public byte[] getPacketArray(boolean reUsable)
                      throws IOException

Description copied from class: StandardPacketInputStream

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

Specified by:

getPacketArray in interface PacketInputStream

Overrides:

getPacketArray in class StandardPacketInputStream

Parameters:

reUsable - if can use existing reusable buffer to avoid creating array

Returns:

array packet.

Throws:

IOException - if socket exception occur.

readMysqlStream

protected void readMysqlStream(byte[] rawBytes,
                               int off,
                               int remaining)
                        throws IOException

Overrides:

readMysqlStream in class StandardPacketInputStream

Throws:

IOException

doTrace

protected void doTrace(int offset,
                       int length,
                       byte[] rawBytes)

Overrides:

doTrace in class StandardPacketInputStream
