Call matching methods from inherited classes

what is the best method to call matching methods from a single class that inherit 3 other base classes with same method name? i want to call those methods from a single call, don't know if it's even possible

template<typename T>
class fooBase()
{
    void on1msTimer();
    /* other methods that make usage of the template */
}

class foo
    : public fooBase<uint8_t>
    , public fooBase<uint16_t>
    , public fooBase<float>
{
    void onTimer()
    {
         // here i want to call the on1msTimer() method from each base class inherited 
         // but preferably without explicitly calling on1msTimer method for each base class
    }
}

Is there any way to do this? Thanks

It is not possible with one call to get all the three member functions at once. Imagine these member functions would return something else than void: which return value would you expect ?!

If you want to call the on1msTimer() of all the three base classes, you need to call these explicitly: 

void onTimer()
{
     fooBase<float>::on1msTimer();
     fooBase<uint8_t>::on1msTimer();
     fooBase<uint16_t>::on1msTimer();
}
