Template Struct Store

Defined in File asset-mgr.h

Inheritance Relationships

Base Type

public CE::Assets::Cache::Context (Class Context)

Struct Documentation

template<typename AssetType, typename Key = std::filesystem::path, typename Allocator = std::allocator<std::pair<const Key, std::shared_ptr<AssetType>>>> struct Store : public CE::Assets::Cache::Context 

Caches constructed assets by key.

reserve() provides storage whose slots callers construct selectively with emplace(); the older allocate() interface returns unconstructed handles for manual construction. Publish complete assets under a unique lock; readers copy retained handles under a shared lock. Construction and final release happen outside the lock.

Public Types

using Handle = std::shared_ptr<AssetType>
