Variables in wrong class
Just found out with my clang static source analyzer: We have
class Z4::AbstractZ4Solver: public exahype::solvers::ADERDGSolver {
public:
static constexpr int NumberOfVariables = 54;
static constexpr int NumberOfParameters = 0;
static constexpr int Order = 3;
class Variables;
class ReadOnlyVariables;
class Fluxes;
...but then
class Z4::Z4Solver::ReadOnlyVariables {
private:
const double* const _Q;
public:
static constexpr int SizeVariables
...However, it should be Z4::AbstractZ4Solver::ReadOnlyVariables or the forward declarations have to change classes.
