ludus::foundation::geometry::PreparedDistanceMap¶

Class

Immutable distance cache for one prepared path revision; move-only.

Built only by TryBuildDistanceMap. A default map is empty, and queries through its view return MissingCache. Single owner; synchronize replacement externally.

Declared in modules/foundation/geometry/include/ludus/foundation/geometry/distance.hpp

Methods¶

PreparedDistanceMap¶

ludus::foundation::geometry::PreparedDistanceMap::PreparedDistanceMap() noexcept=default

Construct an empty map; queries report MissingCache.

Declared in modules/foundation/geometry/include/ludus/foundation/geometry/distance.hpp

PreparedDistanceMap¶

ludus::foundation::geometry::PreparedDistanceMap::PreparedDistanceMap(PreparedDistanceMap &&other) noexcept=default

Transfer the cache; the source becomes empty.

Declared in modules/foundation/geometry/include/ludus/foundation/geometry/distance.hpp

operator=¶

PreparedDistanceMap & ludus::foundation::geometry::PreparedDistanceMap::operator=(PreparedDistanceMap &&other) noexcept=default

Release this cache and take the other's; the source becomes empty.

PreparedDistanceMap¶

ludus::foundation::geometry::PreparedDistanceMap::PreparedDistanceMap(const PreparedDistanceMap &)=delete

Copying is disabled: one owner holds the prepared storage.

Declared in modules/foundation/geometry/include/ludus/foundation/geometry/distance.hpp

operator=¶

PreparedDistanceMap & ludus::foundation::geometry::PreparedDistanceMap::operator=(const PreparedDistanceMap &)=delete

Copy assignment is disabled: one owner holds the prepared storage.

~PreparedDistanceMap¶

ludus::foundation::geometry::PreparedDistanceMap::~PreparedDistanceMap()=default

Release the prepared storage; views into it become invalid.

Declared in modules/foundation/geometry/include/ludus/foundation/geometry/distance.hpp

GetView¶

DistanceMapView ludus::foundation::geometry::PreparedDistanceMap::GetView() const noexcept

Borrow the cache; invalidated by moving or destroying the map.

IsEmpty¶

bool ludus::foundation::geometry::PreparedDistanceMap::IsEmpty() const noexcept

Whether no map has been built into this owner.
