Detailed Description

A Functor (Function Object) that calculates primality.

• Instead of returning a value, it holds a pointer to a ResultQueue and "pushes" its result there once finished.

operator()()

void IsPrimeCalculator::operator() ( ) const

inline

Overloaded operator() to perform the calculation.

• This allows the struct instance to be treated as a void() task by the ThreadPool.

                            {
        bool prime = true;
        if (n <= 1) prime = false;
        else {
            for (int i = 2; i * i <= n; i++) {
                if (n % i == 0) {
                    prime = false;
                    break;
                }
            }
        }
        // Send the result to the orchestrator (Main Thread)
        outputQueue->push({prime, n});
