Question

I have some private variables (say int a, int b, int c) inside my class. Due to some internal manipulations I need to set/get such variables in a thread safe way so I used some wrapping getters/setters and used a scoped mutex.

void setA(int a)
{
    unique_lock<mutex> lock(opMutex);

    this->a = a;
}

void getA(int a)
{
    unique_lock<mutex> lock(opMutex);

    return a;
}

void setB(int b)
{
    unique_lock<mutex> lock(opMutex);

    this->b = b;
}

void setC(int c)
{
    unique_lock<mutex> lock(opMutex);

    this->c = c;
}

My question is: is it possbile to avoid getter/setter methods (public variables) and keep thread safety on assign/read operations over such variables?

Answer 1

There is a similar library in Boost, boost::atomic but it’s not yet included in the standard AFAIK.
