  • c++ - When do we need to define destructors? - Stack Overflow
    When you need to do this, you must define the destructor to be virtual within the base class Otherwise, your derived destructors won't get called, independent of whether they are defined or not, and whether they are virtual or not
  • The difference between a destructor and delete - Stack Overflow
    A destructor is a special method for a class It is called whenever an object goes out of scope, or someone calls it explicitly An example where an objects destructor is called, but no delete: struct MyObject { MyObject() { std::cout << "default constructor"; } ~MyObject() { std::cout << "destructor"; } void doWork() {}; } int main() { { MyObject object; constructor is called and memory
  • C++ Constructor Destructor inheritance - Stack Overflow
    For trivial cases that destructor just calls the base class' destructor, and often that means that there is no explicit code for its destructor (which imitates inheritance) But if a class has members with destructors, the generated destructor calls destructors for those members before calling the base class' destructor
  • Do I need to explicitly call the base virtual destructor?
    When overriding a class in C++ (with a virtual destructor) I am implementing the destructor again as virtual on the inheriting class, but do I need to call the base destructor?

  • c# - When should I create a destructor? - Stack Overflow
    A destructor is then essentially an assurance that if the consumer of your object forgets to dispose it, the resource still gets cleaned up eventually (Maybe ) If you make a destructor be extremely careful and understand how the garbage collector works Destructors are really weird: They don't run on your thread; they run on their own thread
  • The difference between a destructor and a finalizer?
    I believe 'destructor' is the C# code, and the 'finalizer' is the compiled CIL method The C# compiler turns a destructor into a finalizer EDIT: To be more verbose; The C# language specification defines a 'destructor' as a C# instance method on a class 'destructor', then, is part of the C# grammar -- destructors are a linguistic object appearing in source code A destructor is a member that
  • destructor - Confusing with delete and free function in C++ - Stack . . .
    The destructor is more obscure as it is used to release resources that were created in the constructor In your case the constructor allocates memory and the destructor deallocates the memory
  • When to make a destructor defaulted using =default?
    Although using =default for constructors is clear for me (i e forcing the compiler to create the default constructor while other ctors exist), I still cannot understand the difference between thes
