If a
path exists in the multiple inheritance hierarchy that
|
|
|
derives
the common base class as not virtual (i.e., leaving
|
|
out
the keyword virtual), then this turns off virtual
|
|
|
inheritance
for that path and more than one instance of
|
|
|
the
common_base will be formed.
|
|
|
| • |
Virtual
base classes are constructed before any of their
|
|
|
derived
classes. They are also constructed before any non
|
|
|
virtual
base classes. And, destructors are still invoked in
|
|
|
the
reverse order of constructors.
|
|
|
| • |
Any
direct or indirect base classes that have initialization
|
|
|
lists
that invoke the virtual base class constructor are
|
|
|
ignored.
