Summary
In this chapter, we introduced the use of interceptors and decorators in CDI, including how they are enabled within beans.xml of a bean archive.
For interceptors, we explained what a binding type was and how it supported inheritance. We also covered how to use binding and @Nonbinding members of an interceptor binding type, and how different interceptor binding types can be combined on bean types and methods.
We saw a situation in which a decorator is suited to solve a business problem, how to specify that a class implementing a bean type is a decorator, and what delegate object is injected into the decorator.
