Constructor Detail

SerializableParameter

public SerializableParameter(Object object,
                             boolean noBackslashEscapes)
                      throws IOException

Throws:

IOException

Method Detail

writeTo

public void writeTo(PacketOutputStream os)
             throws IOException

Write object to buffer for text protocol.

Parameters:

os - the stream to write to

Throws:

IOException - if error reading stream

writeUnsafeTo

public void writeUnsafeTo(PacketOutputStream os)
                   throws IOException

Write object to buffer for text protocol without checking buffer size.

Parameters:

os - the stream to write to

Throws:

IOException - if error reading stream

getApproximateTextProtocolLength

public long getApproximateTextProtocolLength()
                                      throws IOException

Return approximated data calculated length.

Returns:

approximated data length.

Throws:

IOException - if error reading stream

sendComLongData

public void sendComLongData(int statementId,
                            short parameterId,
                            PacketOutputStream writer)
                     throws IOException,
                            QueryException

Send data in one or many COM_STMT_LONG_DATA. (Data is read is using a big buffer to avoid having a lot of packet, because server will allocate/deallocate array each send)

Specified by:

sendComLongData in class LongDataParameter

Parameters:

statementId - statement id

parameterId - parameter number

writer - writer

Throws:

IOException - if any connection exception occur

QueryException - if query size is to big according to server max_allowed_size

toString

public String toString()

Specified by:

toString in interface ParameterHolder

Overrides:

toString in class Object

getMariaDbType

public MariaDbType getMariaDbType()
