[ndnSIM] Trace application

[narjes aloulou]

Hi,

I want to  trace the download time of a content (zipf consumer). However,  the trace is generated as an empty file. When I debug the code, I found that the method OnData of the zipf-consumer class is not executed.

My questions: when Ondata of the application is executed? what 's the relation between Ondata of the forwarding strategy and OnData of the application?

Best regards
