Chapter 6. Absolute inversion of control
This chapter covers
- Wiring components together dynamically
- Applying method interceptors
- Raising and observing component events
- Resolving context variables on demand
Inversion of control (IoC) is a pattern in aspect-oriented programming (AOP) that espouses loose coupling, allowing the application to focus on consuming services rather than locating them. Seam embraces the use of IoC not only to “wire” components together but also to produce context variables and to enable components to communicate with one another through event notifications.
