示例1: writeData

void TinyLogBlockOutputStream::writeData(const String & name, const IDataType & type, const IColumn & column, WrittenStreams & written_streams)
{
    IDataType::SerializeBinaryBulkSettings settings;
    settings.getter = createStreamGetter(name, written_streams);

    if (serialize_states.count(name) == 0)
        type.serializeBinaryBulkStatePrefix(settings, serialize_states[name]);

示例2: writeData

void NativeBlockOutputStream::writeData(const IDataType & type, const ColumnPtr & column, WriteBuffer & ostr, UInt64 offset, UInt64 limit)
{
    /** If there are columns-constants - then we materialize them.
      * (Since the data type does not know how to serialize / deserialize constants.)
      */
    ColumnPtr full_column = column->convertToFullColumnIfConst();

    IDataType::SerializeBinaryBulkSettings settings;
    settings.getter = [&ostr](IDataType::SubstreamPath) -> WriteBuffer * { return &ostr; };
    settings.position_independent_encoding = false;
    settings.low_cardinality_max_dictionary_size = 0;

    IDataType::SerializeBinaryBulkStatePtr state;
    type.serializeBinaryBulkStatePrefix(settings, state);
    type.serializeBinaryBulkWithMultipleStreams(*full_column, offset, limit, settings, state);
    type.serializeBinaryBulkStateSuffix(settings, state);
