DESIGN PATTERNS JAVA COMPANION
Design patterns began to be recognized more formally in the early
1990s by Helm (1990) and Erich Gamma (1992), who described patterns
incorporated in the GUI application framework, ET++. The culmination of
these discussions and a number of technical meetings was the publication of
the parent book in this series, Design Patterns -- Elements of Reusable
Software, by Gamma, Helm, Johnson and Vlissides.(1995). This book,
commonly referred to as the Gang of Four or “GoF” book, has had a powerful
impact on those seeking to understand how to use design patterns and has
become an all-time best seller. We will refer to this groundbreaking book as
Design Patterns, throughout this book and The Design Patterns Smalltalk
Companion (Alpert, Brown and Woolf, 1998) as the Smalltalk Companion.
