Detailed Description

template<typename T>
class dsf::PtrMapView< T >

Non-owning view over a map of owning pointers, exposing (id, raw pointer) pairs.

The view does not expose the std::unique_ptr, so callers cannot reset or release the owned objects. If T is const, the objects are only accessible as const. The iterators only wrap the map's iterators, so they stay valid after the view itself is destroyed.

Template Parameters

T	The type of the owned objects, optionally const-qualified

Member Function Documentation

at()

template<typename T>

T & dsf::PtrMapView< T >::at ( Id const id ) const

inline

Get an element by id.

Exceptions

std::out_of_range

if no element with the given id exists
