Inheritance diagram for ehm_dal::schema::AbstractUidTableItem:
Public Member Functions | |
| qint32 | uid () const override |
| Returns the row's unique database id. Not all tables use a uid. | |
 Public Member Functions inherited from ehm_dal::schema::AbstractIdTableItem | |
| AbstractIdTableItem () | |
| Default constructor. | |
| virtual | ~AbstractIdTableItem () |
| Default destructor. | |
| virtual void | addChildItem (std::shared_ptr< AbstractIdTableItem > item, const ehm_dal::tables::TableIndex child_table) |
Adds the child item item from the child_table to the present tree table. This represents a tree relationship between the child 'item' from the child table and the present table. | |
| virtual QVariant | childData (const QModelIndex &index, qint32 role, ehm_dal::column_data::ColumnData *column_data, const ehm_dal::tables::TableIndex child_table) const |
Returns child data stored under the given role for the selected index. | |
| virtual qint32 | childItemId (const ehm_dal::tables::TableIndex child_table) const |
Returns the item id number for the child data under the related child_table. | |
| virtual qint32 | childRowCount (const ehm_dal::tables::TableIndex child_table) const |
Returns the number of related child items in respect of child_table. | |
| virtual bool | setChildData (const QModelIndex &index, const QVariant &value, const qint32 role, std::vector< qint32 > &modified_columns, ehm_dal::column_data::ColumnData *column_data, const ehm_dal::tables::TableIndex child_table) |
Sets the role data for the child item at index to value. | |
| qint32 | id () const |
| Returns the row id. The first row of a table is 0, the second row is 1, etc. | |
| QVariant | id (const qint32 role) |
Returns the row id in a manner compatible with QAbstractTableModel item roles. This is generally unecessary and qint32 AbstractIdTableItem::id() should be used where possible. | |
| virtual QString | text () const =0 |
| Returns the row's display text. This provides a convenient way to obtain a simple description of the row. | |
| Q_DECL_DEPRECATED QString | displayText () const |
| virtual qint32 | uid () const |
| Returns the row's unique database id. Not all tables use a uid. | |
| QVariant | data (const qint32 column, qint32 role, ehm_dal::column_data::ColumnData *column_data) const |
Returns the row's data stored under the given role for the column. | |
| virtual QVariant | data (const QModelIndex &index, qint32 role, ehm_dal::column_data::ColumnData *column_data) const |
Returns the row's data stored under the given role for the column referred to by the index. | |
| virtual QString | identifier () const |
| Returns the item's text identifier for matching against. | |
| virtual QStringList | identifierList () const |
Returns a list of all of the item's identifiers for matching against. This includes the main identifier() string as well as any alternatives. | |
| bool | alloc (const qint32 new_id) |
Initialises the table item and allocates and item id to new_id and a uid (if applicable) and then calls init(). This should be called whenever adding a new item to a table. This should not be called during file i/o. | |
| virtual qint32 | parentItemId () const |
| Returns the item id of the items parent item. Applies to tree structures only. | |
| bool | setData (const qint32 column, const QVariant &value, qint32 role, std::vector< qint32 > &modified_columns, ehm_dal::column_data::ColumnData *column_data) |
Sets the role data for the item at column to value. | |
| virtual bool | setData (const QModelIndex &index, const QVariant &value, qint32 role, std::vector< qint32 > &modified_columns, ehm_dal::column_data::ColumnData *column_data) |
Sets the role data for the item at index to value. | |
| virtual void | fixErrors () |
| Fixes any known errors with the item. E.g. errors introduced with a prior version of EHM DAL or the Editor. | |
| Public Member Functions inherited from ehm_dal::schema::AbstractTableItem | |
| AbstractTableItem () | |
| Default constructor. | |
| virtual | ~AbstractTableItem () |
| Default destructor. | |
| virtual bool | read (QDataStream &in, ehm_dal::database::DatabaseVersion &version) |
Reads a table row from the QDataStream. | |
| virtual bool | write (QDataStream &out, ehm_dal::database::DatabaseVersion &version) |
Writes a table row to the QDataStream. | |
| virtual bool | init ()=0 |
| Initialises the table item members. This only needs to be called once per item. | |

Returns the row's unique database id. Not all tables use a uid.
- Returns
- the row unique id. A uid of -1 denotes that no uid has been set.
