public void Load<NodeDataType>( 
   XContainer root,
   Func<XElement,NodeDataType> nodedataallocator
)
where NodeDataType: GraphModelNodeData<NodeKey>

Parameters

root

the XContainer holding all of the data

nodedataallocator

a function that takes an XElement and returns either a newly constructed object of type NodeDataType or null if that XElement is to be ignored

Type Parameters

NodeDataType

this must be a class inheriting from GraphModelNodeData<NodeKey>

This will iterate over all of the child elements of the root container, calling nodedataallocator on each one. If that function returns non-null, it calls LoadFromXElement on the new data and then adds it to the NodesSource collection.

All of the changes to this model are performed within a transaction.

This does not set the IsModified property to false. You may wish to do so, depending on your application requirements. You might also wish to clear the UndoManager.
