public class FileSinkDGSFiltered extends FileSinkBaseFiltered
File output for the DGS (Dynamic Graph Stream) file format. It includes also the possibility to filter dynamic events such as :
For instance :
Graph graph = new SingleGraph("My_Graph"); FileSinkDGSFiltered fileSink = new FileSinkDGSFiltered(); graph.addSink(fileSink); // No need to save the attribute "attr1" of any edges fileSink.addEdgeAttributeFiltered("attr1"); // No need to save graph attributes fileSink.setNoFilterGraphAttributeAdded(false); // Start to listen event fileSink.begin("./my_graph.dgs"); // Make some modifications on the graph and generate events graph.stepBegins(0); // this event will be saved graph.addAttribute("attr2", 2); // this event will not be saved Node a = graph.addNode("A"); // this event will be saved a.addAttribute("attr3", 3); // this event will be saved // and now, no more need to save modification on nodes attributes fileSink.setNoFilterNodeAttributeChanged(false); Node b = graph.addNode("B"); // this event will be saved b.addAttribute("attr4", 4); // this event will not be saved Edge ab = graph.addEdge("AB", a, b); // this event will be saved ab.addAttribute("attr1", 1); // this event will not be saved ab.addAttribute("attr5", 5); // this event will be saved fileSink.end();

Since dynamic graphs are based on discrete event modifications, the notion of step is defined to simulate elapsed time between events. So a step is a event that occurs in the graph, it does not modify it but it gives a kind of timestamp that allow the tracking of the progress of the graph over the time.
This kind of event is useful for dynamic algorithms that listen to the dynamic graph and need to measure the time in the graph's evolution.
graphId
- Identifier of the graph where the step starts.timeId
- A numerical value that may give a timestamp to track the
evolution of the graph over the time.Copyright © 2015. All rights reserved.
