Refresher/SDLC/Delegate and Polymorphism

Presentation
Polymorphism or Delegate: method overloading or method passing Late binding: method looked up by name at run-time and exact behavior determined at run-time Early binding: method name and signature stored in the virtual method table (v-table) at compile time Polymorphism: objects from different types responding to calls by the same name, e.g. operator overloading for addition delegate (function pointers in C++): an object encapsulates reference to a method multicast delegate: a delegate that points to and eventually fires off several methods Delegate: a class -- usable if declared and instantiated Delegate use: passed around as a parameter, and invoked by the receiving object Delegate example 1: success = MyAddressProvider.HandleCampaign(WhatToDoWithAddresses) Delegate example 2: MyMenuItem.Click += new System.Windows.RoutedEventHandlerMyMenuItem_Click)
