ToList (); Storeuserinfo.databind ();} Sorting and filteringAs we have mentioned above, the server side can obtain the sort and filter parameters, and then get the corresponding data by processing the sort and filter.For example, my filter code:UserInfo. GetData (); (filter) {userinfolist = Userinfolist.findall (m = = M.name = = Item. Value); }}This will fi

server receives the request and returns an HTTP response to the Web server resolution request, locating the requested resource. The server writes a copy of the resource to the TCP socket, which is read by the client. A response consists of a status line, a response header, a blank line, and a 4 portion of the response data.(4) Release the TCP connection Web server to actively close the socket, release the TCP connection, and the client passively close the socket, releasing the TCP connection(5)

can be used to store Java objects, which are their same point, but they also differ:①hashtable is based on the old dictionary class, HashMap is an implementation of the map interface introduced by Java 1.2.②hashtable is synchronous, and some methods of this class ensure that objects in Hashtable are thread-safe, and HashMap is asynchronous, so objects in HashMap are not thread-safe. Because the requirements of synchronization affect the efficiency of execution, if you do not need a thread-safe

Originally, BOOL and bool were different. Someone sorted them out and reproduced them. I,1. Different TypesBOOL is int typeBool is Boolean2.

activity dies (isfinishing returns True). In this way, we avoid asynctask errors or any other callback functions that do not notice the activity life cycle.ConclusionAs you can see, Anko provides a common set of programs that simplify our work when we write Android apps. There are many other things, such as the creation of a conversation or the maintenance of a database, which I can read in the next article.But if you really want to take the risk of creating an app with Kotlin, you can start wi

Never call the virtual function in a construct/destructor. Never call virtual functions during construction and destruction.Calling the virtual function in a construct/destructor will cause the link to fail because the compiler will not perform polymorphic operations and pass the virtual function call to the derived class.Here you can give the called function an implementation and add a parameter, which can be passed to the base class when it is called in the derived class.Effective C + + clause

result is the same as the original result, the refactoring ends.3, if the test results are different from the original, in the testing and debugging process, the old algorithm as a comparative reference standard. corresponding to each test case, the new and old 2 algorithms are executed, and observe whether the results of 2 are the same. This can help you see which test case is in trouble and what kind of trouble it has.Summary: Optimization of algorithmsRefactoring to improve existing code des
