Hi Xiangyong,
I do not understand what do you want to do. In case of constraint handler,
there are some so-called "Fundamental Callback Methods", see
http://scip.zib.de/doc/html/CONS.html
This means, your constraint handler has to support these methods and SCIP
checks that these are not a NULL pointer.
Best Stefan
