Function Documentation

QList<const T*> RDB::sortRows	(	IT	it,
		R(T::*)() const	order
	)			[inline]

Sort rows of a table using given property.

The values of the property are compared using operator >.

Parameters:

	it	Row iterator of any kind.
	order	Getter method of the property to use for sorting.

Returns:

The list of rows ordered by the property value. Example:

 RDB::IndexConstIterator<MyRow> it( myTable.index() );
 QList<const MyRow*> rows = sortRows( it, &MyRow::size );

QList<const T*> RDB::localeAwareSortRows	(	IT	it,
		R(T::*)() const	order
	)			[inline]

Sort rows of a table using given property.

The values of the property are compared using QString::localeAwareCompare().

Parameters:

	it	Row iterator of any kind.
	order	Getter method of the property to use for sorting.

Returns:

The list of rows ordered by the property value.

const T* RDB::findRow	(	IT	it,
		R(T::*)() const	method,
		const V &	value
	)			[inline]

Find a row with given value of a non-indexed property in a table.

Parameters:

	it	Row iterator of any kind.
	method	Getter method of the property to check.
	value	The value to find.

Returns:

The first row with given value or NULL if none was found.
