Reflection is often used as part of software testing, such as for the runtime creation/instantiation of mock objects. Reflection is also a key strategy for metaprogramming. In some object-oriented programming languages such as C# and Java, reflection can be used to bypass member accessibility rules. For C#-properties this can be achieved by ...
Programming languages and computing platforms that typically support reflective programming (reflection) include dynamically typed languages such as Smalltalk, Perl, PHP, Python, VBScript, and JavaScript. Also the .NET languages are supported and the Maude system of rewriting logic.
Usually this involves some form of reflection or reflection-like API. As an example of how to use JavaFX objects from Java. [32] For creating and interacting with objects entirely at runtime, e.g., interaction with a document object model abstraction, a specific abstraction API must be used. See also example #Interoperability with dynamic ...
The Ecma standard lists these design goals for C#: [17] The language is intended to be a simple, modern, general-purpose, object-oriented programming language. The language, and implementations thereof, should provide support for software engineering principles such as strong type checking, array bounds checking , [ 20 ] : 58–59 detection of ...
If a library is written in one CLI language, it can be used in other CLI languages. Moreover, apps that consist only of pure .NET assemblies, can be transferred to any platform that contains an implementation of CLI and run on that platform. For example, apps written using .NET can run on Windows, macOS, and various versions of Linux.
The Reflection Library provides the ability to examine the structure of types, create instances of types and invoke methods on types, all based on a description of the type. [11] It defines types in the following namespaces: System Defines the void type, a return value type for a method that does not return a value. System.Globalization
For example, all packages beginning with java are a part of the Java platform—the package java.lang contains classes core to the language, and java.lang.reflect contains core classes specifically relating to reflection. In Java (and Ada, C#, and others), namespaces/packages express
The UML class diagram for the Membership example. UML provides an association class construct for defining reified relationship types. The association class is a single model element that is both a kind of association [6] and a kind of class. [7] The association and the entity type that reifies are both the same model element.
