ClickHouseRowBinaryStream

public ClickHouseRowBinaryStream(OutputStream outputStream,
                                 TimeZone timeZone,
                                 ClickHouseProperties properties)

Method Detail

writeUnsignedLeb128

public void writeUnsignedLeb128(int value)
                         throws IOException

Throws:

IOException

writeBytes

public void writeBytes(byte[] bytes)
                throws IOException

Dangerous. Can only be used for rare optimizations, for example when the string is written in parts without prior concatenation. The size of the string in bytes must be passed through writeUnsignedLeb128.

Parameters:

bytes - byte array will be written into stream

Throws:

IOException - in case if an I/O error occurs

writeByte

public void writeByte(byte b)
               throws IOException

Dangerous. Can only be used for rare optimizations, for example when the string is written in parts without prior concatenation. The size of the string in bytes must be passed through writeUnsignedLeb128.

Parameters:

b - byte value

Throws:

IOException - in case if an I/O error occurs
