  1. Domain-Driven Design Chapters 10-13 Refactoring Towards Deeper Insight CS527 - lecture 15

  2. Patterns • Intention-revealing Interfaces • Side-effect Free Functions • Assertions • Conceptual Contours • Standalone Classes • Closure of Operations • Strategy, Composite CS527 - lecture 15

  3. Assertions in Java • New Java statement in version 1.4 • assert exp1; • assert exp1: exp2; • If exp1 is false, throw an exception and give it exp2 as an argument • http://java.sun.com/j2se/1.4/docs/guide/lang/assert.html CS527 - lecture 15

  4. Conceptual contours • Choose a design that does not have to change when you add new features. • If new features don’t fit into your design, it proves the design was deficient, so go ahead and rewrite it. CS527 - lecture 15

  5. Principles • Model must be readable. • Focus on what model looks like, not on what implementation of model looks like. • Each piece should be simple. • Declarative style CS527 - lecture 15
