Dependency Injection Principles, Practices, and Patterns

11 Tool-based Aspect-Oriented Programming

In this chapter

• Using dynamic Interception to apply Interceptors using generated Decorators
• Advantages and disadvantages of dynamic Interception
• Using compile-time weaving to apply Cross-Cutting Concerns
• Why compile-time weaving is the antithesis of DI

This chapter is a continuation of the Aspect-Oriented Programming (AOP) discussion that we started in chapter 10. Where chapter 10 described AOP in its purest form — namely, applying AOP solely using SOLID design practices — this chapter approaches AOP from a tool-based perspective. We’ll discuss two common methods for applying AOP: dynamic Interception and compile-time weaving.

In case the design approach of chapter 10 is too radical, dynamic Interception ...
