Additional Inherited Members
Public Member Functions inherited from ehm_dal::schema::AbstractTableItem
	AbstractTableItem ()
	Default constructor.
virtual	~AbstractTableItem ()
	Default destructor.
virtual void	addChildItem (std::shared_ptr< AbstractTableItem > 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.
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.
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 AbstractTableItem::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.
virtual bool	init ()=0
	Initialises the table item members. This only needs to be called once per item.
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.
Protected Member Functions inherited from ehm_dal::schema::AbstractTableItem
virtual bool	deletable () const
template<IntegralNumber T>
QVariant	fromHexVector (const std::vector< T > &raw_data, const qint32 role) const
QVariant	fromValue (const QVariant &value, const qint32 role) const
	Returns a value as a QVariant if the role is Qt::DisplayRole or Qt::EditRole. A blank QVariant is returned if another role is selected.
