Description

Unique type identifier for engine resources.

ResourceTypeId assigns a unique, monotonically increasing integer ID to each resource type at compile time. Used by ResourceRegistry as an index into the fastAccess_ array for O(1) type-based resource lookup.

All resource categories (Managers, CommandBuffers, CommandHandlers) share a single index space.

Public Constructors

ResourceTypeId()

helios::engine::runtime::world::types::ResourceTypeId::ResourceTypeId (const size_t id)

inline explicit

Constructs a ResourceTypeId with a specific value.

Parameters

id	The type ID value.

Definition at line 56 of file ResourceTypeId.ixx.

56 explicit ResourceTypeId(const size_t id) : id_(id) {}

ResourceTypeId()

helios::engine::runtime::world::types::ResourceTypeId::ResourceTypeId (helios::ecs::types::no_init_t)

inline explicit

Constructs an uninitialized ResourceTypeId.

Parameters

no_init_t

Tag to indicate no initialization.

Definition at line 64 of file ResourceTypeId.ixx.

64 explicit ResourceTypeId(helios::ecs::types::no_init_t) {}

Public Member Functions

value()

size_t helios::engine::runtime::world::types::ResourceTypeId::value ()

inline noexcept

Returns the underlying ID value.

Returns

The numeric type ID, suitable for use as an array index.

Definition at line 72 of file ResourceTypeId.ixx.

72 [[nodiscard]] size_t value() const noexcept {

73 return id_;

74 }

Private Member Attributes

id_

size_t helios::engine::runtime::world::types::ResourceTypeId::id_ {0}

The underlying ID value.

45 size_t id_{0};

Public Static Functions

id()

template <typename T>

ResourceTypeId helios::engine::runtime::world::types::ResourceTypeId::id ()

inline static

Returns the ResourceTypeId for a specific type.

Uses TypeIndexer to generate a unique ID per type. The ID is generated once and cached.

Template Parameters

T	The resource type.

Returns

The unique ResourceTypeId for type T.

Definition at line 88 of file ResourceTypeId.ixx.

88 [[nodiscard]] static ResourceTypeId id() {

89 static const size_t tid = helios::ecs::TypeIndexer<ResourceType>::typeIndex<T>();

90 return ResourceTypeId(tid);
