Passing data from a notifing function to a listening function

Asked by Collin
on 21 Apr 2016
What are the trade-offs for...
1. Using a custom event.EventData class to pass data from the notifying function to the listening function
2. Using the source argument returned in the listening function to access the data directly
Specifically, a model/state class generates a large data set in a while loop. At the end of each loop, an update event notifies a plotting class of the desire to plot the data. Which data exchange mechanism would have the lest effect of the performance of the while loop.
Thank you
