Description

Unique type identifier for system types.

SystemTypeId assigns a unique, monotonically increasing integer ID to each system type at compile time. Used by SystemRegistry as an index for O(1) type-based system lookup.

Public Constructors

SystemTypeId()

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

inline explicit

Constructs a SystemTypeId with a specific value.

Parameters

id	The type ID value.

Definition at line 51 of file SystemTypeId.ixx.

51 explicit SystemTypeId(const size_t id) : id_(id) {}

SystemTypeId()

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

inline explicit

Constructs an uninitialized SystemTypeId.

Parameters

no_init_t

Tag to indicate no initialization.

Definition at line 59 of file SystemTypeId.ixx.

59 explicit SystemTypeId(helios::ecs::types::no_init_t) {}

Public Member Functions

value()

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

inline noexcept

Returns the underlying ID value.

Returns

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

Definition at line 67 of file SystemTypeId.ixx.

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

68 return id_;

69 }

Private Member Attributes

id_

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

The underlying ID value.

40 size_t id_{0};

Public Static Functions

id()

template <typename T>

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

inline static

Returns the SystemTypeId 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 SystemTypeId for type T.

Definition at line 83 of file SystemTypeId.ixx.

83 [[nodiscard]] static SystemTypeId id() {

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

85 return SystemTypeId(tid);

86 }
