How do I implement the builder pattern in data processing pipelines with C++?

The Builder Pattern is a design pattern that allows you to create complex objects step by step, chaining method calls together to configure the object. This is particularly useful in data processing pipelines where multiple stages of processing are needed. In C++, the Builder Pattern can simplify the construction of pipeline objects and improve the readability of your code.

Here’s an example of how you could implement the builder pattern in a simple data processing pipeline:


class DataProcessor {
    std::string data;
public:
    DataProcessor& setData(const std::string& input) {
        data = input;
        return *this;
    }

    DataProcessor& filter(const std::string& criterion) {
        // Filtering logic here
        data += " | Filtered by: " + criterion;
        return *this;
    }

    DataProcessor& transform(const std::string& operation) {
        // Transformation logic here
        data += " | Transformed with operation: " + operation;
        return *this;
    }

    void process() {
        std::cout << "Final processed data: " + data + "\n";
    }
};

int main() {
    DataProcessor processor;
    processor.setData("Initial Data")
             .filter("Criterion 1")
             .transform("Operation 1")
             .process();
}
