◆ Erase()

bool DataMap::Erase ( std::string const &  k)
inline

Removes objects with given key and returns true if one was removed, false otherwise

70{ return Container.erase(k) != 0; }

◆ Get()

template<class T >
T * DataMap::Get ( std::string const &  k) const
inline

Returns a pointer to object of requested type stored with given key or nullptr

30 {
31 static_assert(std::is_base_of<Base, T>::value, "T must derive from Base");
32 if (Container.empty())
33 {
34 return nullptr;
35 }

37 auto it = Container.find(k);
38 if (it != Container.end())
39 {
40 return dynamic_cast<T*>(it->second.get());
41 }
42 return nullptr;
43 }

◆ GetDefault()

template<class T , typename std::enable_if< std::is_default_constructible< T >::value, int >::type = 0>
T * DataMap::GetDefault ( std::string const &  k)
inline

Returns a pointer to object of requested type stored with given key or default constructs one and returns that one

51 {
52 static_assert(std::is_base_of<Base, T>::value, "T must derive from Base");
53 if (T* v = Get<T>(k))
54 {
55 return v;
56 }
57 T* v = new T();
58 Container.emplace(k, std::unique_ptr<T>(v));
59 return v;
60 }

◆ Set()

void DataMap::Set ( std::string const &  k,
Base v 
)
inline

Stores a new object that inherits the Base class with the given key

65{ Container[k] = std::unique_ptr<Base>(v); }
