Interface GraphAdapter

public interface GraphAdapter

Used as an adapter between an already existing graph model and this collections library.

The graph is supposed to support two things: 1. Ability to determine a specific node in the graph based on an index, 2. Ability to retrieve list of neighbours of a node.

The graph doesn't have to be bi-directional, and the graph adapter doesn't have to be implemented as such.

Method Summary

java.lang.Object	getNode(int index) Retrieves a node at a certain index.
java.lang.Iterable<java.lang.Object>	getNodeNeighbours(java.lang.Object node) Retreves the list of a node's neighbours.
