simply inheriting it when it comes to implementation, and Facebook has an added layer of inheritance for the scalability of the post protocol and for allowing other organizations, teams, or individuals to implement their own data transfer (primarily in data format encapsulation). is the class diagram of the Tvirtualprotocol class, from the name of the class can

points: (1) The abstraction will lose its effect; (2) A second code generator must be maintained; (3) It would be very difficult to maintain compatibility with older versions. Through its advantages and shortcomings of the analysis found that they are so bright, so the choice of this Protocol as a transport layer on the protocol type needs to be considered more carefully, the advantage is the sacrifice of abstraction, easy maintenance and forward

Java list source code analysis, list source code analysis Three Data Structure linked lists, trees, and graphs. As one of them, the sequence table is the longest used in programming. The List interface is the implementation of sequence tables in

Dynamic loading of third party classes using reflection Using reflection to load a third party class is useful:Use XML or other matching files to configure the classes to be loaded, separating from the system source code.Class checking of loaded classes is that the loaded class conforms to its own defined structure. No is the same as the passed-in $par

The following describes the functionality defined by Tserver from the definition of member variables, constructors, and other related functions. 1. Member Variable definition The member variable definition of a class can basically reflect the attributes of a

Thrift Tprotocol Class System principle and source code detailed: Binary Protocol class Tbinaryprotocolt (Tbinaryprotocol) This protocol is the default binary protocol supported by thrift, which writes all the data in a binary format and basically sends the original data directly. Because it inherits directly from the
