8. A ctor can serve in static_cast. 9. Inherited ctors inherits explicit/constexpr properties. It does not inherit default arguments. Instead it gets multiple ctors in which each parameter with a default argument is successively omitted. 10. If a class defines a dtor, even if it uses =def...

To build with MSVC you can use thewin-x64-msvc-staticpreset. This preset (and all presets inheriting from it) need various additional environment variables to be set and you need to install dependencies from various sources: MSYS2_ROOTandMSYS2_PREFIX: for Perl (only used byqtforkawesomeso ...
If a part of the program is able to use the interface, it is able to work with all classes inheriting the interface without knowing those classes in detail. For example a human driver is able to use the interface CarInterface. Every car that implements the CarInterface can be operated ...
Your custom SpineExtension may derrive from DefaultSpineExtension and should overwrite the _alloc, _calloc, _realloc and _free (inheriting the implementation of _readFile). You can then set the extension with a call to spine::SpineExtension::setInstance() on program startup. Alternatively, if...

This gets 44a little more complicated when multiple threads can be trying to retrieve 45the class simultaneously, requiring that we use the class object's monitor 46to keep things orderly. 47 48The linking (preparing, resolving) of a class can cause us to recursively 49load superclasses and ...
