Class Documentation

class ConstWeakArea

used internally by RegulatoryElements to avoid cyclic dependencies.

It works conceptually similar to a std::weak_ptr. This is the immutable version of a WeakArea and returns a ConstArea when lock() is called.

Subclassed by lanelet::WeakArea

Public Types

using ConstType = ConstWeakArea 

using MutableType = WeakArea 

using TwoDType = ConstWeakArea 

using ThreeDType = ConstWeakArea 

Public Functions

ConstWeakArea() = default

inline ConstWeakArea(ConstArea area)

inline ConstArea lock() const

Obtains the original ConstArea.

Throws:: NullptrError – if the managed lanelet expired.

inline bool expired() const noexcept: tests whether the WeakArea is still valid
