Recently, when I used the boost library's smart pointer in my project, I felt that the smart pointer was quite powerful. Here I posted my own tests written during the learning process.CodeFor the reference of other friends who want to know about boost smart pointers. If you have made any mistakes, please poi
First, prefaceToday we opened the Android system article, in fact, have always wanted to get, but has not been too much in-depth understanding, and recently took this piece out of a good look, so want to comb a bit, to see the android in this piece of knowledge, First of all, let's take a look at this: the concept of smart pointers in Android, why first look at the knowledge of smart pointers? Because we lo
Reprinted from: introduction of C + + smart pointer
Because the C + + language does not have an automatic memory recovery mechanism, the programmer will manually delete each new memory. The programmer forgets to delete, the process is too complex, resulting in no delete, and the exception causes the program to quit prematurely, and it is not uncommon to not execute the delete.Using smart pointers can effect
In this issue, you will see how to create a picture effects model using a copy of two homologous smart objects and apply a filter to blur the background. After creating the image effects model, you can change different scenes simply by replacing the material of the smart object.

Why does a smart pointer still need release? Isn't it necessary to manage the reference count? Why?ProgramMember to release?
The reason is that the smart pointer object releases the interface pointed to when the object is destroyed, but if you destroy the com library before the function exits, you need to release it in advance.
For example:
: Coinitialize (null); // If Initialization is performed here
PS students know that there is such a thing, called smart object.
What exactly does it have in the egg?
A, smart object differs from a normal layer, which retains the source content of the image and all its original attributes.
In other words, no matter how you scale the selection of smart objects, it will not lose the original information.

"Structure is always subject to function, which is the constant law," said construction engineer Louis Sullivan, "the father of skyscrapers." Because engineers don't want innocent people to be crushed under huge buildings, this thumbs-up rule is quite useful. In design you should always focus on functionality, and then let the structure appear in the results. If you focus on structure,
I'm sure everyone knows about the three major wireless 3G standards. Therefore, there is a unique and advanced technology in the TD wireless technology, which is different from the other two technologies-smart wireless technology, that is, smart antenna technology.

Smart pointer template classA smart pointer is a class object that behaves like a pointer, but this object has additional functionality.

technical standards are amazing. The boost portability standard ensures that your library works normally when you move your code from one platform to another. The latest version is boost 1.25.0, from smart pointers to regular expressions to portable thread libraries. Boost currently supports 35 libraries, all of which have been tested and used by members of the community. These libraries are free of charge, and many of them have been used for commerc

Since the C ++ language does not have an automatic memory reclaim mechanism, the programmer must manually delete the new memory each time. When the programmer forgets to delete, the process is too complex and eventually leads to the absence of delete, exceptions lead to premature exit of the program, and the absence of delete execution is not uncommon.
