To abstract the objects in the real world into Euclidean point, line, surface, etc. ignores the complexity of the state and evolution process of the objects in the real world. Combining the knowledge of philosophy, physics, mathematics and geography, this paper puts forward the concept of ...
aRaster data can be defined as an abstraction of the real world where spatial data is expressed as a matrix of cells or pixels, with spatial position implicit in the ordering of the pixels. The pixel value indicates the attribute, such as color, elevation, or ID number 光栅数据可以被定义...
WF represents a logical next step in this march toward higher levels of programming abstraction. WF programs execute within a special runtime environment that itself runs on the .NET CLR. The WF runtime environment imposes some restrictions on the developer authoring programs that target it. But ...
Stream abstraction has a long list of useful functions. Let us look at a few of them. Before moving ahead, let us build aListof strings beforehand. We will build our examples on this list so that it is easy to relate and understand. List<String>memberNames=newArrayList<>();memberNames....

Containers can be considered a platform, an app layer abstraction, or a virtualized OS that helps package everything coded for an app in one machine in the form of a bundled image or a file. This bundle, for instance, will consist of all libraries, resources, codes, etc., required to ...
Note: In the above examples, the class hierarchy is very straightforward. The JackRussellTerrier class has a single parent class, Dog. In real-world examples, the class hierarchy can get quite complicated. The super() function does much more than just search the parent class for a method or...
To demonstrate a few examples where filters can improve the design of an ASP.NET MVC Core app, I’ve built a simple API that provides basic create, read, update, delete (CRUD) functionality and follows a few standard rules for handling invalid requests. Because securing APIs is its...
Machine Learning is a sub-domain of Artificial Intelligence wherein algorithms are programmed to learn through experiences. It uses complex, high-level statistical means to impart reasonable intelligence to computers. Once ML training sets have had enough throughput in terms of data, they can automate...
In real-world examples, the class hierarchy can get quite complicated. The super() function does much more than just search the parent class for a method or an attribute. It traverses the entire class hierarchy for a matching method or attribute. If you aren’t careful, super() can have...
