Detailed Description

SQLite-backed storage for the flight log.

Owns the app's user-data SQLite database (userdata.db, shared with other user data that may be added later, e.g. an aircraft list) and persists the 'flights' table within it.

Per-operation persistence: each method here writes only the row(s) it names, rather than reconciling the whole table against an in-memory list. FlightLog still keeps its own in-memory QList<Flight> (the app's dataset is small enough that this costs nothing, and most of FlightLog's logic — sorting, uuid lookups, export selection — is naturally list-shaped); this class exists purely to keep the on-disk copy in sync with each individual change as it happens.

Constructor & Destructor Documentation

FlightLogStorage()

Flightlog::FlightLogStorage::FlightLogStorage ( QObject * parent )

explicit

Standard constructor.

Opens (creating if necessary) the userdata.db SQLite database and ensures the 'flights' table schema exists.

Parameters

parent

The standard QObject parent pointer

Member Function Documentation

loadAll()

auto Flightlog::FlightLogStorage::loadAll ( ) -> QList< Flight >

nodiscard

Load all flights from the database.

Returns

All flights currently stored, in unspecified order

remove()

bool Flightlog::FlightLogStorage::remove

(

const QUuid &

uuid

)

Delete a flight by uuid.

Does nothing (and still returns true) if no row with this uuid exists.

Parameters

uuid	The uuid of the flight to delete

Returns

True on success

removeAll()

bool Flightlog::FlightLogStorage::removeAll

(

)

Delete every flight.

Returns

True on success

removeMany()

bool Flightlog::FlightLogStorage::removeMany

(

const QList< QUuid > &

uuids

)

Delete multiple flights by uuid, in one transaction.

Parameters

uuids

The uuids of the flights to delete

Returns

True on success

saveError

void Flightlog::FlightLogStorage::saveError ( const QString & message )

signal

Emitted when a database operation fails.

Always delivered via a queued connection, so it is safe to emit from the constructor (before any signal connections exist yet).

Parameters

message

Human-readable error description

upsert()

bool Flightlog::FlightLogStorage::upsert

(

const Flight &

flight

)

Insert a flight, or update it if its uuid already exists.

Parameters

flight

The flight to persist

Returns

True on success

upsertMany()

bool Flightlog::FlightLogStorage::upsertMany

(

const QList< Flight > &

flights

)

Insert or update multiple flights, in one transaction.

Parameters

flights

The flights to persist

Returns

True on success
