31. Juli 2019 · In short, a virtual function defines a target function to be executed, but the target might not be known at compile time. Unlike a non-virtual function, when a virtual function is overridden the most-derived version is used at all levels of the class hierarchy, rather than just the level at which it was created.
8. Jan. 2012 · Non-virtual member functions are resolved statically. member function are binding statically at compile-time based on the type of the pointer (or reference) to the object. In contrast, virtual member functions are binding dynamically at run-time.
- Though virtualism/dynamic dispatch is strictly implementation defined, most(read all known ) compilers implement it by using vptr and vtable ....
- If you have a base class 'Base' and derived class 'Derived' and you have a function 'func()' defined as virtual in Base class. This func is overrid...

- When calling a virtual method, it has to look up which function to call in a virtual function table.
- The overhead of calling a virtual method is significant. Also this.
The virtual thunk is for virtually inherited classes, which only have 1 special object within the object rather than multiple. If you didn't virtually inherit, there would be multiple of those objects within the object, and youd use a non virtual thunk to offset them when calling a method in the most derived class
A nonvirtual bus is analogous to a structure in C code. Use nonvirtual buses to: Construct an array of buses. Have bus data cross MATLAB Function block or Stateflow ® chart boundaries. Package bus data as structures in generated C code. Interface with external code through an S-function.

Nonvirtual blocks play an active role in the simulation of a system. If you add or remove a nonvirtual block, you change the model behavior. Virtual blocks help organize a model graphically. While they play no active role in the simulation, they can affect the execution order of other blocks.
