Is it valid to call some function in destructor with this argument?
Function does not store pointer, but assume full-functional object.
回答1:
this is still valid in the destructor.
However, you need bear in mind that virtual functions no longer work properly as you might expect once the object is being destroyed; see e.g. Never Call Virtual Functions during Construction or Destruction. Essentially, the dynamic type of the object is modified as each destructor completes.
回答2:
In one word: YES.
It's fully valid to use this in the D`TOR
