Constructor Detail

DecompressPacketInputStream

public DecompressPacketInputStream(InputStream in,
                                   int maxQuerySizeToLog,

Method Detail

getPacket

public Buffer getPacket(boolean reUsable)
                 throws IOException

Specified by:

getPacket in interface PacketInputStream

Specified by:

getPacket in class AbstractPacketInputStream

Throws:

IOException

getPacketArray

public byte[] getPacketArray(boolean reUsable)
                      throws IOException

Get next packet. Packet can be compressed, and if so, can contain many standard packet.

Specified by:

getPacketArray in interface PacketInputStream

Specified by:

getPacketArray in class AbstractPacketInputStream

Parameters:

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

Returns:

array packet.

Throws:

IOException - if socket exception occur.

readMysqlStream

                       byte[] rawBytes)

Specified by:

doTrace in class AbstractPacketInputStream

getCompressLastPacketSeq

public int getCompressLastPacketSeq()

Specified by:

getCompressLastPacketSeq in interface PacketInputStream
