Interface Replayable

All Known Implementing Classes:

AbstractGraph, AdjacencyListGraph, DefaultGraph, MultiGraph, SingleGraph, Timeline

public interface Replayable

Defines sources that can be replayed. This is usefull when you are connecting a sink to a source but you need to get informations about the current state of the dynamic graph.

 Replayable source = ... ;
 Replayable.Controller replay = source.getReplayController();
 ...
 // source is building a graph
 ...
 Graph g = ... ;
 //
 // Replay the source to get the current state of the graph
 //
 replay.addSink(g);
 replay.replay();

Method Detail

getReplayController

Replayable.Controller getReplayController()

Get a controller to replay the graph.

Returns:

a new replay controller

replay

static void replay(Replayable source,
                   Sink sink)

Util method to replay a replayable source into a sink.

Parameters:

source - a source implementing the Replayable interface

sink - sink which will receive the events produced by the replay

tryReplay

static void tryReplay(Source source,
                      Sink sink)

Same as replay(Replayable, Sink) but the first parameter is just a Source and it will be replayed only if the Replayable interface is implemented.

Parameters:

source - a source

sink - sink which will receive the events produced by the replay
