Reuse c++ modules in c++ code

Hi,
I am writing a new c++ signal processing block and wondering if I can
use existing gnuradio modules in this new module. I know reuse c++
modules in python is easy via swig. When it comes to reusing in c++,
what is the best way? I can think of inheritance. But what if I want to
use multiple existing modules? Maybe I should use composition, and in my
work(), I should call work() of all embeded modules?
Regards
Kyle

It is possible to write hierarchical blocks in C++, which compose
existing blocks into an internal flowgraph:

You do not need to call the work() function of the internal blocks;
the runtime figures all this out for you.
