Hello,
let's say I want my users to use only one class, say SpecialData.
Now, this data class would have many methods, and depending on the type of data, the methods do different things, internally, but return externally similar results. Therefore my wanting to have one "public" class and other "private", child classes that would change the behavior of methods, etc...
It would be amazingly more simple for some types of data that need to be built to do something like this:
SpecialData& sm = SpecialData::new_supermatrix();
and new_supermatrix() would return a SuperMatrix instance, which inherits from most behaviors of SpecialData.
my header:
static SpecialData& new_supermatrix();
my cpp:
SpecialData& SpecialData::new_supermatrix()(){
return SuperMatrix(MATRIX_DEFAULT_MAGNITUDE,1000,1239,FLOAT32,etc...);
}
The problem is, I get this error, which is probably logical due to the circumstances:
invalid initialization of non-const reference of type ‘SpecialData&’ from a temporary of type ‘SpecialData’
So, any ideas?
