where NodeDataType: GraphLinksModelNodeData<NodeKey>
where LinkDataType: GraphLinksModelLinkData<NodeKey,PortKey>

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

linkdataallocator

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

Type Parameters

NodeDataType

this must be a class inheriting from GraphLinksModelNodeData<NodeKey>

LinkDataType

this must be a class inheriting from GraphLinksModelLinkData<NodeKey,PortKey>

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. It will then iterate again over all of the child elements of the root container, calling linkdataallocator on each one. If that function returns non-null, it calls GraphLinksModelLinkData<NodeKey,PortKey>.LoadFromXElement on the new data and then adds it to the LinksSource 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.
