Detailed Description

The Row class provides an interface for retreiving and submitting entries from the database.

The Row class is a base class and when instantiated, the appropriate subclass should be used.

The database holds all the data related to the logbook in different tables. Each of these tables is composed of rows. Each row has different columns and each column contains the data. As such, an entry can be thought of as a row in the database. The row class encapsulates the data contained in each row.

A row is uniquely identified by its position in the database, consisting of the table name (QString) and the row id (int). A new entry, which is not yet in the database has the row id 0. If a new row object is created, the hasData bool is set to false. Before submitting the entry to the database, setData() has to be called to fill the row with data and toggle the verification bit.

The Row Object holds all the necessary information the Database class needs to commit (create or update) it. The Identifying information can be accessed with getRowId and getTable() / getTableName().

For convenience and readabilty, subclasses exist that have the table property pre-set. These rows are then referred to as entries. See AircraftEntry, FlightEntry etc.
