Decouples an abstraction so two classes can vary independently. Takes a group of objects into a single object. Provides a simple interface to a more complex underlying object.
Reduces the cost of complex object models. Provides a placeholder interface to an underlying object to control access, reduce cost, or reduce complexity. Behavior Design Patterns Chain of Responsibility. Delegates commands to a chain of processing objects. Creates objects which encapsulate actions and parameters.
Implements a specialized language. Accesses the elements of an object sequentially without exposing its underlying representation. Allows loose coupling between classes by being the only class that has detailed knowledge of their methods. Provides the ability to restore an object to its previous state.
Allows an object to alter its behavior when its internal state changes. Allows one of a family of algorithms to be selected on-the-fly at run-time.
Template Method. Defines the skeleton of an algorithm as an abstract class, allowing its sub-classes to provide concrete behavior. Separates an algorithm from an object structure by moving the hierarchy of methods into one object. Piyush April 28, at am. RAVI November 4, at pm. Shankar Krishna November 15, at am.
