Interface ClassAdapter

All Superinterfaces:

Cloneable, org.jboss.util.JBossInterface

All Known Implementing Classes:

ReflectClassAdapter

public interface ClassAdapter

extends org.jboss.util.JBossInterface

A class adapter.

A class adapter is the integration point for manipulating class information at runtime, e.g. overriding annotations or obtaining an aop instance advisor.

The class adapter has the following protocol.

1. Use getClassInfo to obtain information about the class.
2. Obtain an Instance ClassAdapter if the class information should be overridden at the instance level, e.g. annotations
3. Obtain the dependencies of the Class/Instance and any advice factories, e.g. @Depends annotations
4. Obtain the JoinpointFactory so the instance can be constructed.

FIXME: This class deals with too many concerns FIXME: Need a mechanism to allow different use cases for the unadvised case. i.e. whether in the absence of aop requirements the adapter should give a proxy advisor, instrument the class for aop anyway or default back to reflection (most likely!)
