Creating a single thread for multiple objects

Question

I have a thread which I am creating whenever an object is created of the class , the thread I am creating in the constructor itself. So, depending on how many objects are created , the number of threads will be equal to number of objects created. But I want to create only a single thread , no matter how many objects are created..

Any help would be appreciated.

I can't put the code here as it is too big. A simple suggestion will be helpful for me.

Answer 1

You can use singleton design pattern to restrict an object to have one (or specific number of) instance(s). Moreover, look at this for a thread safe implementation if you create object from multiple threads.

Answer 2

I would suggest to move thread into separate class and make its static object in your main class te something like this

MyThreadClass {
    // implement your code to handle thread
};

MyObjectClass {
    static MyThreadClass* myThread; // static object to keep single thread  
};

main() {
    // create multiple MyObjectClass 
}

I made very simple code to check this concept with std::thread
