asset::EntryID< TY > Struct Template Reference
#include <entry-id.hpp>
Detailed Description
template<class TY>
struct asset::EntryID< TY >
typed symbolic and hash ID for asset-like position accounting.
Allows for creating an entry with symbolic id and distinct type, combined with an derived hash value, without the overhead in storage and instance management imposed by using a full-fledged Asset.
Similar to an Asset, an identification tuple is available (generated on the fly), as is an unique LUID and total ordering. The type information is attached as template parameter, but included into the hash calculation. All instantiations of the EntryID template share a common baseclass, usable for type erased common registration.

The type information TY will be included automatically into the generated hash-ID. This hash is reproducible.

- Returns:
- true if the upcast would yield exactly the same tuple (symbol,type) as was used on original definition of an ID, based on the given BareEntryID. Implemented by re-calculating the hash.
