Class GraphModel

java.lang.Object
  com.vinculumtech.carrierwave.graphmodel.GraphModel

public class GraphModel

extends java.lang.Object

The GraphModel class is intended as a simple abstraction for managing the relationships in an ImageGraph instance. Use the GraphModel to remove instances of an Image completely from the graph, or to dynamically walk the graph, or to retrieve a whole graph via a ImageSource. After instantiating an instance of GraphModel, resolve it so that that model matches the underlying ImageGraph. From there add or remove Vertices or Edges from the model. During this process the ImageGraph instance will be in an inconsistent state. Sync the model when the changes are complete.
