GenerativeSeamFinder.PixelGraph

java.lang.Object
- seamcarving.GenerativeSeamFinder.PixelGraph

All Implemented Interfaces:

Graph<Node>

Enclosing class:

GenerativeSeamFinder
```
private static class GenerativeSeamFinder.PixelGraph
extends Object
implements Graph<Node>
```
Generative adjacency list graph of GenerativeSeamFinder.PixelGraph.Pixel vertices and EnergyFunction-weighted edges. Rather than materialize all vertices and edges upfront in the constructor, generates vertices and edges as needed when neighbors(Node) is called by a client.
