[dune-pdelab] Inquiry

[Jared Okiro]

Dear PDELab Members,

I am requesting for clarification on the example code in the directory
dune-pdelab-howto/src/convection-diffusion/dgdiffusion.cc.
In the section for calculating the L2 error(commented), there is a line like
this:

*typedef DifferenceSquaredAdapter<G,UDGF> DifferenceSquared;*

Can someone help me understand which type is G?. Apparently I dont see it
declared
anywhere in the code. Can I adapt the *" class  DifferenceSquaredAdapter* "
to determine the L2
error of my solution?.
Kind regards,
