class rmf_traffic::schedule::Patch

A container of Database changes.

Public Types

using base_iterator = rmf_traffic::detail::bidirectional_iterator<E, I, F>
using const_iterator = base_iterator<const Participant, IterImpl, Patch>

Public Functions

Patch(std::vector<Participant> changes, rmf_utils::optional<Change::Cull> cull, std::optional<Version> base_version, Version latest_version)

Constructor. Mirrors should evaluate the fields of the Patch class in the order of these constructor arguments.

Parameters

  • [in] changes: Information about how the participants have changed since the last update.

  • [in] cull: Information about how the database has culled old data since the last update.

  • [in] base_version: The base version of the database that this Patch builds on top of.

  • [in] latest_version: The lastest version of the database that this Patch represents.

const_iterator begin() const

Returns an iterator to the first element of the Patch.

const_iterator end() const

Returns an iterator to the element following the last element of the Patch. This iterator acts as a placeholder; attempting to dereference it results in undefined behavior.

std::size_t size() const

Get the number of elements in this Patch.

const Change::Cull *cull() const

Get the cull information for this patch if a cull has occurred.

std::optional<Version> base_version() const

Get the base version of the Database that this patch builds on.

If this is a nullopt, then this patch does not need to build off of any base version.

Version latest_version() const

Get the latest version of the Database that informed this Patch.

class Participant

Public Functions

Participant(ParticipantId id, ItineraryVersion itinerary_version, Change::Erase erasures, std::vector<Change::Delay> delays, Change::Add additions, std::optional<Change::Progress> progress)

Constructor

Parameters

  • [in] id: The ID of the participant that is being changed

  • [in] itinerary_version: The version of this participant’s itinerary that results from applying this patch

  • [in] erasures: The information about which routes to erase

  • [in] delays: The information about what delays have occurred

  • [in] additions: The information about which routes to add

  • [in] progress: Information about progress that the participant has made since the last change, if any.

ParticipantId participant_id() const

The ID of the participant that this set of changes will patch.

ItineraryVersion itinerary_version() const

The itinerary version that results from this patch.

const Change::Erase &erasures() const

The route erasures to perform.

These erasures should be performed before any other changes.

const std::vector<Change::Delay> &delays() const

The sequence of delays to apply.

These delays should be applied in sequential order after the erasures are performed, and before any additions are performed.

const Change::Add &additions() const

The set of additions to perfom.

These additions should be applied after all other changes.

const std::optional<Change::Progress> &progress() const

Progress that this participant made since the last version, if any.
