ObjectiveThe Point Cloud Library (PCL) is a powerful, open-source C + + library that will help us greatly in the field of LIDAR data processing if a good PCL can be used. LiDAR technology after several decades of development, at home and abroad on the LiDAR point cloud data processing has been very rich, but there are still hardware development speed is greater t

For the average user, the improved Safari browser and calendar apps have become richer and more user-friendly. However, the official version of the Mavericks system will need to meet with consumers in the fall. It is not clear whether Apple, which knows the way of marketing, has a "repertoire" l

Forms of dependency Injection
The basic idea of the dependency injection is to have a separate object, an attacker, that populates a field in the Lister class with an appropriate implementation for the finder interface, resulting in a dependency dimo-along the lines of Figure 2

Turn: Dependency Injection principle
Dependency Injection principle posted on 2015-08-01 | Categories in Software Engineering | 3 Reviews 0. Preface
In the field of software engineering, Dependency injection (Dependency injection) is one of the most common ways to implement control inversion (inversion of controls). This paper mainly introduces the principle of dependency injection and the common way of implementation, with emphasis on introducing the application scenarios and advantages of thi
What is dependency injection?Dependency Injection (Dependency injection) is one of the design patterns. The name is more abstract, but the problem to be solved is quite clear. For a given application, it is necessary to use some relatively separate components to complete the function. In general, the process of using these components is included in the application's logical statements. The problem is that when these components want to make plug-in functionality similar to the application's busin
