Scaffolding is a technique supported by some model–view–controller frameworks, in which the programmer can specify how the application database may be used.The compiler or framework uses this specification, together with pre-defined code templates, to generate the final code that the application can use to create, read, update and delete database entries, effectively treating the templates ...
import sugar let variable = collect (newSeq): for item in @[-9, 1, 42, 0,-1, 9]: item + 1 assert variable == @[-8, 2, 43, 1, 0, 10] The comprehension is implemented as a macro that is expanded at compile time, you can see the expanded code using the expandMacro compiler option:
Record insertion in MongoDB with Robomongo 0.8.5. The primary interface to the database has been the mongo shell. Since MongoDB 3.2, MongoDB Compass is introduced as the native GUI. There are products and third-party projects that offer user interfaces for administration and data viewing. [48]
Another example in JavaScript uses the built-in methods of Array: filter somethings . filter ( x => x . count > 10 ) . sort (( a , b ) => a . count - b . count ) . map ( x => x . name ) Note that in JavaScript filter and map return a new shallow copy of the preceding array but sort operates in place.
In C#, class methods, indexers, properties and events can all be overridden. Non-virtual or static methods cannot be overridden. The overridden base method must be virtual, abstract, or override. In addition to the modifiers that are used for method overriding, C# allows the hiding of an inherited property or method.
All business logic should be encapsulated onto the domain objects.This principle is not unique to naked objects; it is a strong commitment to encapsulation.; The user interface should be a direct representation of the domain objects, with all user actions consisting of creating, retrieving, or invoking methods on domain objects.
Resource acquisition is initialization (RAII) [1] is a programming idiom [2] used in several object-oriented, statically typed programming languages to describe a particular language behavior. In RAII, holding a resource is a class invariant , and is tied to object lifetime .
The Razor syntax is a template markup syntax, based on the C# programming language, that enables the programmer to use an HTML construction workflow. [ clarification needed ] Instead of using the ASP.NET Web Forms (.aspx) markup syntax with <%= %> symbols to indicate code blocks, Razor syntax starts code blocks with an @ character and does not ...
