Attempt to write a templated locator for Model (as in MVC). Views and controller can receive this object to use what they need.

ModelLocator.h

#include "stdafx.h"
#pragma once

using namespace std;
class ModelLocator
{
    map<string, AGObject*> m_models;
public:
    ModelLocator() {}
    ~ModelLocator() {}

    /* find a model based on a type */
    template<class ModelClass>
    AGIntrusivePtr<ModelClass> findModel() const
    {
        map<string, AGObject*>::const_iterator it = m_models.find(typeid(ModelClass).name());
        AGASSERT(it != m_models.end(), "Invalid model %s", typeid(ModelClass).name());
        return dynamic_cast<ModelClass*>(it->second);
    }

    /* register a model, any existing instance will be erased */
    template<class ModelClass>
    void registerModel(AGIntrusivePtr<ModelClass> model)
    { 
        m_models[typeid(ModelClass).name()] = model.get();
    }

    /* to register a model with a different typename (should check if types are compatible) */
    template<class ModelClass, class ModelClassID>
    void registerModel(AGIntrusivePtr<ModelClass> model)
    { 
        m_models[typeid(ModelClassID).name()] = model.get();
    }
};
