Document directory HTTP Channel TCP Channel Introduction Microsoft. NET Remoting provides a framework that allows an object to interact with another object through an application domain. This framework provides a variety of services, including activation and storage support, and communication channels responsible for message transmission with remote applications. The formatter is used to encode and decode a message before it is transmitted through a channel. Applications can use binary encod

A cookie class is provided in the Java servlet with two parameters representing the name and value of the cookie, respectively. The cookie class provides various methods for setting the cookie's properties, such as the Setmaxage () method to set the cookie's lifetime. If the

join rows. Next, it creates an execution plan based on the compiled plan. This execution plan contains instructions with all logical references translated to actual objects, and tracking mechanism s for query execution. Finally, the server starts execution from the top of the instruction tree. Creating A compiled plan is expensive because the server needs to find the optimal plan out of hundreds of potential Candi Dates. Distinguishing between compile and execution helps overall server performa

Building an application in. NET that requires the use of distributed objects, and the lifetime of the distributed objects is controlled by the client. Your requirements include being able to pass objects by value or by reference, whether they reside on the same computer, on different computers residing on the same local area network (LAN), or on different computers residing on a wide area network (WAN).Implementation strategyThis mode provides two imp

a shared_ptr and want to avoid replication due to performance reasons. Use the underlying pointer or reference the underlying object. This allows the caller to use the object, but does not share ownership or extend the lifetime. If the caller creates a shared_ptr from the original pointer, the new shared_ptr is independent of the original one and does not control the underlying resources. This option is used when the agreements between the caller and

. The class in the method accesses a local variable in the same method, but must add a final. (2). The reason is the difficulty of compiling a program: The life cycle of an inner class object exceeds the lifetime of a local variable. The lifetime of a local variable: When the method is called, the local variables in the method are created in the stack, and when the method call is finished, the stack is reti

: This file must be included in the first line of the file, and can be used in the same way as the session of the file. The above is just a simple tutorial. in practical applications, you can encapsulate it more professionally. the reference code is as follows:SessionMysql. class. php Db = Base: loadModel ('sessionmodel'); $ this-> lifetime = Base: loadConfig ('system', 'session _ lifetime '); session_se

This article to you to share is the PHP implementation of Web Caching tool class code and the use of methods, very practical, the need for small partners can refer to the next. When the PHP program is resistant to high-traffic access, dynamic sites are often difficult to parry, so introduce a caching mechanism that typically has two types of caches First, the file cache Second, the data query result cache, using memory to implement the cache This example uses the file cache primarily. The main

? That's because two different ways to delete a variable! The first: The lifetime of the cookie is set, except that its value is set to NULL by default, and the lifetime is the same as the browser, the browser When off, cookies are deleted! So when you reopen a browser, the output address, you will find that the cookie variables are all deleted! Comment out the two Setcookie () function sections in 2.php (r

because the particle transmitter can color the provided image with the color we want. It is also a good idea to make the particle image translucent, so that the particle system can mix the particles themselves together (you can understand how it works through a few different image files ). .

object address obtained through OBSERVER_PTR will be empty. Why call it a weak pointer, I do not know how the concept of the author is how to think, personal feelings may be because it is only a record of the object address, do not participate in the lifetime management of the object, so called weak. I do not know if you think so, anyway, I think so, haha. when it comes to the question, why do we need multiple mentally retarded pointers? Isn't that m
