Constructor & Destructor Documentation

QueryHandle()

gaia::ecs::QueryHandle::QueryHandle ( QueryId  id, uint32_t  gen  )

inline

Constructs a handle from query slot metadata.

Parameters

id	Query slot identifier.
gen	Query slot generation.

Member Function Documentation

gen()

GAIA_NODISCARD auto gaia::ecs::QueryHandle::gen ( ) const

inline

Returns the query slot generation.

Returns

Generation stored in the handle.

id()

GAIA_NODISCARD auto gaia::ecs::QueryHandle::id ( ) const

inline

Returns the query slot identifier.

Returns

Query slot identifier stored in the handle.

operator!=()

GAIA_NODISCARD constexpr bool gaia::ecs::QueryHandle::operator!= ( const QueryHandle &  other ) const

inlineconstexprnoexcept

Compares packed query handles for inequality.

Parameters

other

Handle to compare.

Returns

True when slot identifier or generation differs.

operator==()

GAIA_NODISCARD constexpr bool gaia::ecs::QueryHandle::operator== ( const QueryHandle &  other ) const

inlineconstexprnoexcept

Compares packed query handles.

Parameters

other

Handle to compare.

Returns

True when slot identifier and generation match.

value()

GAIA_NODISCARD auto gaia::ecs::QueryHandle::value ( ) const

inline

Returns the packed handle representation.

Returns

Combined query identifier and generation bits.
