Interface that is used for manipulating a managed view of an IGraph that supports folding operations like expanding and collapsing of nodes.Namespace: yWorks.yFiles.UI.Model
Assembly: yWorks.yFilesSilverlight.Viewer (in yWorks.yFilesSilverlight.Viewer.dll) Version: 184.108.40.206
The FoldingManager creates views of a MasterGraph and MasterHierarchy which are created using copies of the original "master" entities. The views are being synchronized via the MasterGraph, but may contain additional view state. Typically nodes and edges are being copied from the MasterGraph and they share many of their properties by reference (e.g. Style). However if group nodes are being represented by collapsed group nodes in this view, they maintain a separate set of labels, ports, bends, and geometry. This view-local state is shared between all views that have been created by the same Manager and can be obtained and modified via the FoldingManager's GetViewState methods for dummy edges and dummy nodes in the absence of a corresponding view instance. Developers typically don't need to implement this interface themselves, rather an implementation is provided by the framework and can be obtained from the FoldingManager. Use CreateManagedView()()()() to obtain an IGraph implementation that contains an implementation of this class in its Lookup(Type) method:
This interface extends the interface. This can be used to easily monitor the validity of this view. Also changes to the LocalRoot property will be published via this event.
FoldingManager manager = new FoldingManager(); IFoldedGraph foldedGraph = manager.CreateManagedView(); IGraph graph = foldedGraph.Graph; // obtain the foldedGraph instance using the lookup, this // will yield the same instance as above but can be used // at other places in the code that have access to the graph // instance, only. foldedGraph = graph.GetFoldedGraph();
