org.graphstream.ui.swingViewer.ViewerPipe
public class ViewerPipe
Shell around a proxy pipe coming from the viewer allowing to put viewer listeners on a viewer that runs in a distinct thread.
This pipe is a probe that you can place in the event loop between the viewer and the graph. It will transmit all events coming from the viewer to the graph (or any sink you connect to it). But in addition it will monitor standard attribute changes to redistribute them to specify "viewer listeners".
As any proxy pipe, a viewer pipe must be "pumped" to receive events coming from other threads.

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.
stepBegins
in interface ElementSink
sourceId
- 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.
