In software engineering, the delegation pattern is an object-oriented design pattern that allows object composition to achieve the same code reuse as inheritance. In delegation, an object handles a request by delegating to a second object (the delegate). The delegate is a helper object, but with the original context.
As a precursor to the lambda functions introduced in C# 3.0, C#2.0 added anonymous delegates. These provide closure-like functionality to C#. [3] Code inside the body of an anonymous delegate has full read/write access to local variables, method parameters, and class members in scope of the delegate, excepting out and ref parameters.
Objects delegate their interaction to a mediator object instead of interacting with each other directly. The objects interact with each other indirectly through a mediator object that controls and coordinates the interaction. This makes the objects loosely coupled. They only refer to and know about their mediator object and have no explicit ...
Most publications declined to reveal the whistleblower's identity; Tom Kuntz, editor of RealClearInvestigations, defended the site's decision to publish the article. [26] Cannon stated that whistleblower protections did not ensure anonymity from journalism, instead guaranteeing protection from firing, prosecution, and professional punishment.
This reference can then be stored in a delegate-type variable or passed to a method through a delegate parameter for later invocation. C# delegates support covariance and contravariance, and can hold a reference to any signature-compatible static method, instance method, anonymous method or lambda expression.
Stop-and-copy garbage collection in a Lisp architecture: [1] Memory is divided into working and free memory; new objects are allocated in the former. When it is full (depicted), garbage collection is performed: All data structures still in use are located by pointer tracing and copied into consecutive locations in free memory.

SharpDevelop was designed as a free and lightweight alternative to Microsoft Visual Studio, and contains an equivalent feature for almost every essential Visual Studio Express feature and features very similar to those found in Borland Kylix and Delphi, including advanced project management, code editing, application compiling and debugging functionality.
