multiple inheritance, Google the "dreaded diamond". Java 8 adds default and static methods to interfaces which have traditionally been Java's answer to multiple inheritance. These bring it closer to C++ multiple inheritance, probably a good thing although I've yet to encounter it much in the ...
A a2 = new C(); 1. 2. 3. a1,a2两个虽然都是A类对象,但各自的f()不同。这正是子类型多态的体现。 接口和抽象类: 接口可以继承接口,不能实现接口;抽象类不可以继承接口,但可以实现接口。详见:http://stackoverflow.com/questions/22498245/one-uncertainty-on-multiple-inheritance-in-universal-image-loa...
Multiple-Inheritance Using Interface Here, we willimplement multiple-inheritance by inheriting a class and an interface into the derived class. PHP code to implement multiple-inheritance using the interface The source code toimplement multiple-inheritance using the interfaceis given below. The given pro...
GPO inheritance You can configure a policy setting in more than one GPO, which might result in GPOs conflicting with each other. In this case, the precedence of the GPOs determines which policy setting the client applies. A GPO with higher precedence prevails over a GPO with lower pre...

As you can see in Raymond's example of multiple inheritance, there are two IUnknown vtables. It is illegal for each of them to return a pointer to itself when QI'd for IUnknown; the implementation must consistently pick one of them every time. So now it's pretty clear what we mus...
