-= Non-Implemented Methods
-
-Due to the database connection inherent to the SQLContainer, some of the methods
-from the container interfaces of Vaadin can not (or would not make sense to) be
-implemented. These methods are listed below, and they will throw an
-[classname]#UnsupportedOperationException# on invocation.
-

-public boolean addContainerProperty(Object propertyId,
-                                    Class<?> type,
-                                    Object defaultValue)
-public boolean removeContainerProperty(Object propertyId)
-public Item addItem(Object itemId)
-public Object addItemAt(int index)
-public Item addItemAt(int index, Object newItemId)
-public Object addItemAfter(Object previousItemId)
-public Item addItemAfter(Object previousItemId, Object newItemId)

-Additionally, the following methods of the [classname]#Item# interface are not
-supported in the [classname]#RowItem# class:
-

-public boolean addItemProperty(Object id, Property property)
-public boolean removeItemProperty(Object id)

-== About the getItemIds() method
-
-To properly implement the Vaadin [classname]#Container# interface, a
-[methodname]#getItemIds()# method has been implented in the
-[classname]#SQLContainer#. By definition, this method returns a collection of
-all the item IDs present in the container. What this means in the
-[classname]#SQLContainer# case is that the container has to query the database
-for the primary key columns of all the rows present in the connected database
-table.
-
-It is obvious that this could potentially lead to fetching tens or even hundreds
-of thousands of rows in an effort to satisfy the method caller. This will
-effectively kill the lazy loading properties of [classname]#SQLContainer# and
-therefore the following warning is expressed here:
-
-
-[WARNING]
-====
-It is highly recommended not to call the [methodname]#getitemIds()# method,
-unless it is known that in the use case in question the item ID set will always
-be of reasonable size.
