I have a need to store an instance of a template class in each vertex of
a adjacency_list. I was wondering if my idea below will do:
template
class Home
{
public:
uint32_t id;
House_Type type;
Number_Type digits;
};
The following classes are specific instances of the Home class:
class Ranch_Home : public Home
{}
class Tudor_Home : public Home
{}
I was thinking that the property to store this would have to be
something allows for either Home type to be stored at a vertex.
struct house_obj{};
typedef property < house_obj,
boost::shared_ptr< Home< House_Type_Base,
Digit_Type_Base> > >
VertexProperty;
In this case the House_Type_Base and Digit_Type_Base what I am not sure
about here.
I want to use a Factory to create the appropriate Home based on a string
I read from the file as was seen above. For example, for each line of
the file I plan on using a boost spirit parser to parse the file since I
need all three elements before calling the factory.
1 "Ranch" 20
2 "Tudor" 20509.0
So how can I use the property when the template arguments are objects
that have no common base class between them?
