Behavioral Patterns

Behavioral patterns deal with object collaboration and delegation, focusing on how objects interact and distribute responsibility.

Patterns​

  • Strategy - Define a family of algorithms and make them interchangeable
  • Observer - Define one-to-many dependency between objects
  • Command - Encapsulate a request as an object
  • Template Method - Define skeleton of algorithm in base class
  • Iterator - Access elements of collection sequentially
  • State - Allow object to alter behavior when internal state changes
  • Chain of Responsibility - Pass request along a chain of handlers until one handles it
  • Interpreter - Define a grammar and an interpreter for sentences in that language
  • Mediator - Define an object that encapsulates how a set of objects interact
  • Memento - Capture and restore an object's internal state without breaking encapsulation
  • Visitor - Define a new operation on elements of an object structure without changing their classes
