org.graphstream.stream.GraphReplay

All Implemented Interfaces:

Source

public class GraphReplay
extends SourceBase
implements Source

A simple source of graph events that takes an existing graph and creates a flow of events by enumerating all nodes, edges and attributes of the graph.

The only method of this class is replay(Graph) that takes a graph as argument and :

• First exports all graph attributes as attribute-addition events.
• Then exports all nodes as node-creation events.
  • For each node exports all the node attributes as attribute-addition events.
• Then exports all edges ad edge-creation events.
  • For each edge exports all the edge attribute as attribute-addition events.

In this order.

Note that this is a source, not a pipe. This means that it has its own identifier and is a producer of "new" events. Also note that is does not export the dynamics of the graph, only its structure at the present time (the evolution of the graph is not stored in the graph, to produce a dynamic flow of events of the evolution of a graph you have to register the sinks in the graph itself just after its creation).
