Along the way he offers insights into pattern differences and how to apply the pattern in the simplest possible way. Coverage includes: A catalog of 27 pattern-directed refactorings, featuring examples of real-world code description of twelve design smells that indicate the need for this book's refactorings General information and new insights about patterns and mechanisms of implementation of the refactoring Details:? How low-level refactorings are combined to implement high-level patterns Some ways to apply the same pattern and when to use each Practical ways to get started even if you have little experience with patterns or refactoring?
