Inheritance diagram for experimental::ADatabase:

Signals
void	dataBaseUpdated ()
	updated is emitted whenever the database contents have been updated. This can be either a commit, update or remove. This signal should be used to trigger an update to the models of the views displaying database contents in the user interface so that a user is always presented with up-to-date information.

Detailed Description

The DB class encapsulates the SQL database by providing fast access to hot database data.

Member Function Documentation

◆ customQuery()

QVector< QString > experimental::ADatabase::customQuery	(	QString	statement,
		int	return_values
	)

Can be used to send a complex query to the database.

Parameters

query	- the full sql query statement
returnValues	- the number of return values

◆ database()

QSqlDatabase experimental::ADatabase::database ( )

static

Can be used to access the database connection.

Returns: The QSqlDatabase object pertaining to the connection.

◆ getAircraftEntry()

AAircraftEntry experimental::ADatabase::getAircraftEntry ( RowId row_id )

retreives a TailEntry from the database.

This function is a wrapper for DataBase::getEntry(DataPosition), where the table is already set and which returns an AAircraftEntry instead of an AEntry. It allows for easy access to an aircraft entry with only the RowId required as input.

◆ getFlightEntry()

AFlightEntry experimental::ADatabase::getFlightEntry ( RowId row_id )

retreives a flight entry from the database.

This function is a wrapper for DataBase::getEntry(DataPosition), where the table is already set and which returns an AFlightEntry instead of an AEntry. It allows for easy access to a flight entry with only the RowId required as input.

◆ getPilotEntry()

APilotEntry experimental::ADatabase::getPilotEntry ( RowId row_id )

retreives a PilotEntry from the database.

This function is a wrapper for DataBase::getEntry(DataPosition), where the table is already set and which returns a PilotEntry instead of an Entry. It allows for easy access to a pilot entry with only the RowId required as input.

◆ getTailEntry()

ATailEntry experimental::ADatabase::getTailEntry ( RowId row_id )

retreives a TailEntry from the database.

This function is a wrapper for DataBase::getEntry(DataPosition), where the table is already set and which returns a TailEntry instead of an Entry. It allows for easy access to a tail entry with only the RowId required as input.
