public class OppNetGraph extends org.graphstream.graph.implementations.MultiGraph implements OppNet, Runnable, Closeable
A OppNetGraph represents a network composed of devices (OppNode) linked by edges (OppEdge) representing actual or possible connections between them. Multiple edges can exist between two nodes, each edge representing a connection between the nodes through a specific connectivity type (OppEdge.getConnectivityType()), provided both nodes support the connectivity type (OppNode.hasConnectivityType(String)). The graph is dynamic: it is runnable (play() and stop() methods). At each step, its nodes move and edges are updated accordingly: edges are added (resp. removed) if the nodes are (resp. no more) in mutual radio range according to their connectivity types (areInRange(OppNode, OppNode, String)). The steps are characterized by a simulation time. The simulation can run in real time or not (accelerated or slowed down). This class has two main subclasses: OppNetGraphDGS if the simulation is run according to an input DGS file and OppNetGraphWalk if the simulation is run according to a mobility model (see Walk).
