template<typename Type, typename Loader, typename Allocator>
class entt::resource_cache< Type, Loader, Allocator >
Basic cache for resources of any type.
- Template Parameters
-
| Type | Type of resources managed by a cache. |
| Loader | Type of loader used to create the resources. |
| Allocator | Type of allocator used to manage memory and elements. |
Definition at line 153 of file cache.hpp.
template<typename Type , typename Loader , typename Allocator >
Returns an iterator to the beginning.
If the cache is empty, the returned iterator will be equal to end().
- Returns
- An iterator to the first instance of the internal cache.
Definition at line 251 of file cache.hpp.
template<typename Type , typename Loader , typename Allocator >
template<typename... Args>
Force loads a resource, if its identifier does not exist.
Arguments are forwarded directly to the loader and consumed only if the resource doesn't already exist.
- Warning
- If the resource isn't loaded correctly, the returned handle could be invalid and any use of it will result in undefined behavior.
- Template Parameters
-
| Args | Types of arguments to use to load the resource if required. |
- Parameters
-
| id | Unique resource identifier. |
| args | Arguments to use to load the resource if required. |
- Returns
- A pair consisting of an iterator to the inserted element (or to the element that prevented the insertion) and a bool denoting whether the insertion took place.
