Design Patterns: Elements of Reusable Object-Oriented Software
Book
Design Patterns: Elements of Reusable Object-Oriented Software is a software engineering book describing recurring solutions to common problems in software design. The book is divided into two parts, with the first two chapters exploring the capabilities and pitfalls of object-oriented programming, and the remaining chapters describing 23 classic software design patterns. The book includes examples in C++ and Smalltalk.
Patterns
Strategy
Behavioral Pattern
The strategy pattern is used to create an interchangeable family of algorithms from which the required process is chosen at run-time.
Template Method
Behavioral Pattern
The template method pattern is used to define the basic steps of an algorithm and allow the implementation of the individual steps to be changed.
Visitor
Behavioral Pattern
The visitor pattern is used to separate a relatively complex set of structured data classes from the functionality that may be performed upon the data that they hold.
