Interface1. Multiple unrelated classes can implement the same interface2, a class can implement a number of unrelated interfaces3. Similar to inheritance, there is polymorphism between interface and implementation class4. Define the syntax format for Java classes} Report:1, interface (interface) is the combination of the abstract method and the definition of the
Because PROCFS's default action function uses only one page of caching, it is a bit cumbersome to handle large proc files, and is less flexible when outputting data from a series of structs, requiring you to implement iterations in the Read_proc function, which is prone to bugs. So kernel hackers to some/proc code to do research, abstract common, eventually formed the seq_file (Sequence file: Sequence files) interface. This
Unity has some quirks about their inspector, so as a preface they is listed here:
if you add A[serializable" attribute to a class, Unity ' s Inspector'll attempt to show all Public fields inside that class.
any class Extendingmonobehaviour automatically has the[serializable" attribute
unity ' s inspector would attempt to display any private field with The[serializefield" attribute.
unity s Inspectorwill not attempt to display generic types or interfaces, with the exception of
List InterfaceThe list interface is a sub-interface of the collection interface, the abstract method in the list interface, and a part of the method and his parent interface collection is the same, the list interface's own unique method, with the function of indexing .

Familiar with the previous Citrix landing interface of the full black classic and later white theme, perhaps many people are not satisfied with these two themes.

Class and Object oriented:
Display interface (explicit interface): that is, visible in the source code, you can see all the interfaces of the class in the header file;
Run-time polymorphism (Runtime polymorphism): A member function is virtual, when a reference or pointer to a class is passed, the interface is automatically matched at run time, possibly the
