This article demonstrates a test example of the Loki functor template class in the wince environment. It mainly demonstrates the usage of the following functor: Use the function to initialize LOKI: functor Use functor to initialize LOKI: functor Use the class member function to initialize LOKI: functor Use other

Recently, the project needs to manage resources in multiple threads. Naturally, it comes to the idea of using smart pointers with reference counting technology to construct a garbage collection and recycling mechanism. The first consideration is the use of smartptr in Loki, which is already running in the project. Now we can see that Loki: smartptr is not as flexible as we think. The problem is that the con

Recently, I made a project that is complicated and I want to use smart pointers to manage memory. There is very little information on the Internet, and I have studied a Loki smartptr. Loki Installation 1, download the source code, the latest version is the loki-0.1.7, extract. 2. compile the project under the src directory, and the generated static library is un

C + + three major libraries boost, Loki, STLportin C + +, the position of the library is very high. Mr. Bjarne Stroustrup, the father of C + +, has repeatedly expressed the view that designing a library to augment functionality is better than designing more grammatical words. In reality, the Library of C + + has a wide variety of problems, and the solution is extremely extensive, from lightweight to heavyweight. A lot of people are eye-opening, or loo

The typelist _ ** macro in Loki is too difficult to use because it cannot support variable parameters. Based on the idea of tuple in boost, this typelist_maker is implemented: Template Class T6 = nulltype, class T7 = nulltype, class T8 = nulltype, class T9 = nulltype, class t10 = nulltype,Class T11 = nulltype, class T12 = nulltype, class t13 = nulltype, class T14 = nulltype, class T15 = nulltype,Class T16 = nulltype, class t17 = nulltype, class T18 =

In a twinkling of an eye, the design model has learned so much. I think the design pattern is actually how to abstract and make use and implementation more reasonable. These practices make our software easier to cope with changes. The bridging mode learned a few days ago. When a change is oriented to two or more dimensions, we adopt a combination of abstract methods to deal with the change.What combination abstraction? Let's take a look at th

objects. The design pattern is great. We should learn it. This chapter is over. Thank you. Haha :) In addition to the question. In my opinion, the focus of understanding the design pattern is not on how to draw class diagrams,CodeHow to write. It is true that the code can intuitively express the intent and usage of a design pattern, and at the same time it l

The importance of the design pattern is unnecessary. Various design patterns are widely used in actual projects. I. Simple factory mode and factory Mode I know a little about UML. When I look at this class diagram, I know what the factory model is for. To put it bluntly, it is to provide an abstract base class interface, so that you do not need to remember the name of the new class to be generated. See the following section.Code: # Inclu

In all mode designs, there are three basic design modes: Singleton mode, factory mode, and registration tree mode. Other models are often based on these models, next, let's take a look at the basic php design model (registration tree model, factory model, and single-column model). If you need a friend, come and learn. Let's talk a little bit about it. Let's first introduce the registration tree model, then introduce the factory model, and finally introduce the single-column model. This article i
