stepBegins

public void stepBegins(String sourceId, long timeId, double step)

Description copied from interface: ElementSink

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.

Specified by:

stepBegins in interface ElementSink

Parameters:

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.
