options - connection options

threadId - thread id

Method Detail

create

public static byte[] create(byte[] value)

Constructor for single Data (using text format).

Parameters:

value - value

Returns:

Buffer

create

public static byte[] create(byte[][] row,
                            ColumnType[] columnTypes)

Create Buffer with Text protocol values.

Parameters:

row - row data

columnTypes - column types

getPacket

public Buffer getPacket(boolean reUsable)
                 throws IOException

Specified by:

getPacket in interface PacketInputStream

Throws:

IOException

getInputStream

public InputStream getInputStream()

Get current input stream for creating compress input stream, to avoid losing already read bytes in case of pipelining.

Specified by:

getInputStream in interface PacketInputStream

Returns:

input stream.

getPacketArray

public byte[] getPacketArray(boolean reUsable)
                      throws IOException

Set server thread id.

Specified by:

setServerThreadId in interface PacketInputStream

Parameters:

serverThreadId - current server thread id.

isMaster - is server master

setTraceCache
