class mola::WorldModel

Overview

The main class for a “map” or “world model”.

This class cannot be factored out into its independent module due to its tight connection to “mola-kernel/interfaces”.

Methods

void map_load_from(mrpt::serialization::CArchive& in)

Loads the map from a given source.

Parameters:

std::runtime_error

in case of any I/O error.

void map_load_from(const std::string& fileName)

overload

void map_save_to(mrpt::serialization::CArchive& out) const

Saves the map to the given data sink.

Parameters:

std::runtime_error

in case of any I/O error.

std::string map_base_directory() const

Returns the directory where entities will be swapped-off to disk when unloaded, i.e. the map database directory. This directory is built at construction from MOLA_MAP_STORAGE_DIR and the map name, which by default is the current date and time.

std::set<id_t> entity_neighbors(const id_t id) const

Returns all entities that are connected to a given one by any common factor.

virtual void initialize(const Yaml& cfg)

This must be implemented to read all the required parameters

This should be reimplemented to read all the required parameters

virtual void spinOnce()

Runs any required action on a timely manner

virtual int launchOrderPriority() const

The WorldModel is launched first, before most other modules.
