Hi !
Yet another question about something I quite don't understand : in the Generations view, as shown in http://www.yourkit.com/docs/yjp2014/hel ... ations.jsp, why don't the "retained size" values add up so that they match the total retained size ?
Best regards,
Yannis
Why per generation retained size don't add up ?

Hi Yannis
Retained sizes do not sum up by their nature:
http://www.yourkit.com/docs/java/help/sizes.jsp
In this particular case, retained sets of different generations can intersect.
For example, assume 3 objects: A from generation 1, B from 2 and C from 3.
Let A retain B, B retain C.
Generation 1 retained set will include A,B,C.
Generation 2 retained set will include B,C.
Generation 3 retained set will include C.
Note that size of B and C is counted in multiple generations.

Anton

Yeah, I saw the light later on after posting my question, which was obviously stupid...
Sorry for that and thanks for your answer !
