How reactingParcel updates it date after reaction?
 

Hi, guys, I'm crying out desperately for help. I'm developing a new reacting particle class. But how can I update its particle compositions by chemical reaction?
I think in the existing reactingParcel class function calc() is used to do it, but I didn't see the correspondent reactingCloud call this calc() function. Can someone explain a little about how reactingParcel reactes?
