Detailed Description

template<typename T>
struct commrat::Output< T >

Single output specification.

Specifies that a module produces exactly one output type. Used with PeriodicInput, LoopInput, or Input<T> to define module behavior.

Template Parameters

T	The payload type to be published

Process Signature:

• With PeriodicInput: void process(T& output)
• With Input: void process(const U& input, T& output)
• With Inputs<U, V>: void process(const U& in1, const V& in2, T& output)

// Periodic sensor reading
class SensorModule : public Module<Registry, Output<TempData>, PeriodicInput> {
protected:
    void process(TempData& output) override {
        output.temperature = read_sensor();
    }
};
 
// Event-driven filtering
class FilterModule : public Module<Registry, Output<Filtered>, Input<Raw>> {
protected:
    void process(const Raw& input, Filtered& output) override {
        output.value = apply_filter(input.value);
    }
};
