Hi Georg,
not sure whether there is a nice DuMuX property way to achieve what you
want, but C++11 offers std::conditional.

[DuMuX] Setting Properties

2016-01-28 Thread Georg.Futter 
Hello Dumuxers,

I have a question concerning the property system. Is it possible to set a 
property depending on the value of another property? I have something in mind 
like this:

SET_PROP(MyProblem, MyProperty)
{
private:
enum { boolValue = GET_PROP_VALUE(TypeTag, MyBoolValue) };
public:
if(boolValue)
typedef Dumux::ClassA type;
else
typedef Dumux:: ClassB  type;
};

Obviously the code has a wrong syntax.
Is there a syntax which could be used to do what I want or do I need to pass 
the property value (boolValue ) to the Class and then use class specializations?


Best regards

Georg Futter
