Interface Vertex

All Superinterfaces:

GraphNode, java.util.Map<java.lang.String,java.lang.Object>

public interface Vertex
extends GraphNode

A Vertex represents a user or a resource in the social graph. TODO: The original granite GraphNode get vertices APIs do not support pagination. This is a difficult problem to solve. For example, when we retrieve followings activities of a user, we need to retrieve all the followed users to construct the query of the activity stream.
