, for some function libraries (such as DirectX), we want others to use functions in the library, but do not want to expose the implementation details of the function to the consumer. The usual approach is to provide the function's declaration only to the consumer of the function, and the consumer knows how to call the function based on the function declaration. For a specific function implementation, it is written in a separate function implementation file, either through a dynamic link library

, ‘user_info.html‘, {‘obj‘: obj})This is similar to the default values, except that the data that needs to be updated is passed in here.Add extra FieldsFor example, a login login application scenario. In addition to the user name and password on the page, you can also add a radio box "Remember Me." This extra field is not recorded in the database, but is written in a cookie or session. In this case, the field can be defined in the Modelform class as a public property (static property), defined a

disadvantage of using macro code is error-prone, and the preprocessor often produces unintended marginal effects when copying macro code. In a C + + program, you should replace all macro code with an inline function, and assert assert is probably the only exception. member functions defined in the class declaration will automatically become inline functions The C + + compiler will automatically generate four default functions for a, such as A (void); Default parameterless constructo

expansion, Because there is no need to replicate the original queue, it may be more efficient in some cases.It is also important to note that both implementations are not thread-safe and are therefore only suitable for use in single-threaded environments, and the Linkedblockingdeque described in the following sections are thread-safe and deque. In fact, it should be the most powerful queue implementation, and of course it might be a bit more complicated to implement.In layman's Java Concurrency
