| Name | Description | |
|---|---|---|
 | AddCollectionCopy | Copy existing data and add to this model. |
| AddLink | Add a link between one node/port and another node/port. |
| AddNode | Add a node data to NodesSource. |
| AddNodeCopy | Add a copy of a node data to this model. |
| ChangeModel | This is called during an Undo or a Redo to actually make state changes to this model or to this model's data. |
| ClearUnresolvedReferences | Forget all unresolved delayed or forward references. |
| CommitTransaction | Call the UndoManager's CommitTransaction method. |
| CreateCopyDictionary | Create an ICopyDictionary initialized for this model. |
| CreateDataCollection | Create an empty IDataCollection for this model. |
| CreateInitializedCopy | Create a copy of this model initialized with different data. |
| DoNodeAdded | This should be called when a node data object is added to the NodesSource collection. |
| DoNodeKeyChanged | This should be called when a node data's key value may have changed. |
| DoNodeRemoved | This should be called when a node data object is removed from the NodesSource collection. |
| FindNodeByKey | Given a key, find the node data with that key. |
| GetCategoryForNode | To help distinguish between different kinds of nodes, each node has a "category" that is just a string. |
| GetConnectedNodesForNode | Return a sequence of node data that are directly connected to a given node, in either direction. |
| GetFromNodesForNode | Return a sequence of node data that are directly connected by links going into a given node. |
| GetNodeType | Return the Type of the node data. |
| GetToNodesForNode | Return a sequence of node data that are directly connected by links coming out from a given node. |
| IsLinked | This predicate is true if there is a link from one node data/port to another one. |
| IsLinkValid | This predicate is true if adding a link between two nodes/ports would result in a valid graph. |
| IsNodeData | This predicate is true if the argument is a node data in this model. |
| IsNodeType | This predicate is true when the argument is an instance of the node data Type. |
| RaiseChanged | Raise a Changed event, given a ModelChangedEventArgs. |
| RemoveLink | Remove all links connecting the two nodes/ports in the one direction. |
| RemoveNode | Remove node data from NodesSource. |
| RollbackTransaction | Call the UndoManager's RollbackTransaction method. |
| StartTransaction | Call the UndoManager's StartTransaction method. |
