Private Constructors

StateTypeId()

helios::engine::state::types::StateTypeId::StateTypeId (const size_t id)

inline explicit

Private constructor for internal use.

Parameters

id	The type ID value.

33 explicit StateTypeId(const size_t id) : id_(id) {}

Public Member Functions

value()

size_t helios::engine::state::types::StateTypeId::value ()

inline nodiscard noexcept

Returns the underlying ID value.

Returns

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

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

50 return id_;

51 }

Private Member Attributes

id_

size_t helios::engine::state::types::StateTypeId::id_ {0}

Public Static Functions

id()

template <typename T>

StateTypeId helios::engine::state::types::StateTypeId::id ()

inline nodiscard static

Gets the StateTypeId for a specific component type.

Uses TypeIndexer to generate a unique, monotonically increasing ID for each component type. The ID is generated once per type and cached.

Template Parameters

T	The component type. Must be a concrete type (not abstract).

Returns

The unique StateTypeId for type T.

Definition at line 64 of file StateTypeId.ixx.

64 [[nodiscard]] static StateTypeId id() {

65 static const size_t tid = helios::core::data::TypeIndexer<StateType>::typeIndex<T>();

66 return StateTypeId(tid);
