typename ToContentType< T >::type ToContentType_t
static RDirectory & Heap()
Dedicated, process-wide RDirectory.
Internal::RDirectoryEntry Find(std::string_view name) const
Find the RDirectoryEntry associated to the name.
std::shared_ptr< ToContentType_t< T > > Get(std::string_view name)
Get the object for a key.
void Add(std::string_view name, const std::shared_ptr< T > &ptr)
Add an existing object (rather a shared_ptr to it) to the RDirectory.
std::unordered_map< std::string, Internal::RDirectoryEntry > ContentMap_t
The directory content is a hashed map of name => Internal::RDirectoryEntry.
EFindStatus
Status of the call to Find<T>(name).
@ kValidValue
Value known for this key name and type.
@ kValidValueBase
Value known for this key name and base type.
@ kTypeMismatch
The provided type does not match the value's type.
@ kKeyNameNotFound
No key is known for this name.
ContentMap_t fContent
The RDirectory's content.
std::pair< Internal::RDirectoryEntry, EFindStatus > Find(std::string_view name) const
Find the RDirectoryEntry associated with the name.
std::shared_ptr< ToContentType_t< T > > Create(std::string_view name, ARGS &&... args)
Create an object of type T (passing some arguments to its constructor).
