Pattern Hatching : Design Patterns Applied

John Vlissides








Software developers now recognize the value of design patterns in helping build better software more efficiently. As a result, design patterns have become extremely popular in the software development community. Pattern Hatching explains and enhances the information from the seminal work in the field, Design Patterns: Elements of Reusable Object-Oriented Software. The hands-on approach offered by John Vlissides, co-author of Design Patterns, enables you to better understand the pattern development process, and therefore identify and write your own patterns. The author's insights will further allow you to apply the original 23 patterns by example. Foreword.
