RooTrace Class Reference
RooFit package » Roofitcore

Class RooTrace controls the memory tracing hooks in all RooFit objects.

When tracing is active, a table of live RooFit objects is kept that can be queried at any time. In verbose mode, messages are printed in addition at the construction and destruction of each object.
