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 writing directly onto the (usually invisible) backing field of a non-public property.
Reflection is the API used to read CLI metadata. The reflection API provides a logical view of metadata rather than the literal view provided by tools like metainfo. Reflection in version 1.1 of the .NET framework can be used to inspect the descriptions of classes and their members, and invoke methods.
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.
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.
Modifiers for property accessors: private - Makes the accessor private. protected - Makes the accessor protected. public - Makes the accessor public. The default modifiers for the accessors are inherited from the property. Note that the accessor's modifiers can only be equal or more restrictive than the property's modifier.
Go does not support classes and usually dependency injection is either abstracted by a dedicated library that utilizes reflection or generics (the latter being supported since Go 1.18 [37]). [38] A simpler example without using dependency injection libraries is illustrated by the following example of an MVC web application.
They can be defined on classes, member variables, methods, and method parameters and may be accessed using reflection. In Python , the term "marker interface" is common in Zope and Plone . Interfaces are declared as metadata and subclasses can use implementsOnly to declare they do not implement everything from their super classes.
