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

The factory pattern is a creational design pattern that provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created. It is particularly useful in data processing pipelines where you might have various stages of processing that require different classes of processors.

Here's a brief example of how to implement this pattern in a data processing context. In this example, we will create a pipeline that processes numerical and text data.


    // Base Processor Interface
    class Processor {
    public:
        virtual void process() = 0;
    };

    // Concrete Processor Classes
    class NumberProcessor : public Processor {
    public:
        void process() override {
            // Logic for processing numbers
            std::cout << "Processing numbers..." << std::endl;
        }
    };

    class TextProcessor : public Processor {
    public:
        void process() override {
            // Logic for processing text
            std::cout << "Processing text..." << std::endl;
        }
    };

    // Factory Class
    class ProcessorFactory {
    public:
        static Processor* createProcessor(const std::string& type) {
            if (type == "number") {
                return new NumberProcessor();
            } else if (type == "text") {
                return new TextProcessor();
            }
            return nullptr;
        }
    };

    // Usage
    int main() {
        Processor* numberProcessor = ProcessorFactory::createProcessor("number");
        numberProcessor->process();
        
        Processor* textProcessor = ProcessorFactory::createProcessor("text");
        textProcessor->process();
        
        delete numberProcessor;
        delete textProcessor;
        return 0;
    }
