THistogramArrayBase and inheritance from std::vector

[Former user]

Hello

THistogramArrayBase is considered as a polymorphic class (according to examples).

Unfortunately, this class itself has a public inheritance from non-polymorphic std::vector that has no virtual destructor.

This issue is explained, for example, here: https://stackoverflow.com/a/4357417

It is possible to use composition instead of inheritance?

Thanks

i agree, looks like a mistake. I myself avoid extending standard library classes. K.O.

basically, if it does not have a virtual destructor, one should not extend it. this is the best I understand the situation in c++. beats me why c++ does not enforce this. also read:
