Struct Documentation

template<typename T>
struct LayerView : public navmap::LayerViewBase

Typed layer view storing one T value per NavCel.

Note

Elements are indexed by navmap::NavCelId.

Template Parameters:

T – Scalar type (uint8_t, float, double).

Element access (indexed by NavCelId).

inline T &operator[](NavCelId cid)

inline const T &operator[](NavCelId cid) const

Layer hashing & access

inline std::vector<T> &mutable_data() const

inline void set_data(const std::vector<T> &v)

virtual std::uint64_t content_hash() const override

Return 64-bit content hash (cached; recomputed lazily).

Public Functions

inline LayerView(std::string name, size_t nitems, LayerType t)

Construct a typed view.

Parameters:

• name – Layer name.

• nitems – Number of NavCels.

• t – Runtime type tag corresponding to T.

inline virtual LayerType type() const override

Returns:

Type tag of the underlying storage.

inline virtual const std::string &name() const override

Returns:

Layer name (unique within the registry).

inline virtual size_t size() const override

Returns:

Number of items (= number of NavCels).

inline std::vector<T> &data()

Returns:

Mutable reference to internal storage.

inline const std::vector<T> &data() const

Returns:

Const reference to internal storage.
