Package javassist.tools.reflect
(also recently known as interceptors or AOP?)
This package enables a metaobject to trap method calls and field
accesses on a regular Java object. It provides a class
Reflection, which is a main module for implementing
runtime behavioral reflection.
It also provides
a class Loader and Compiler
as utilities for dynamically or statically
translating a regular class into a reflective class.
An instance of the reflective class is associated with
a runtime metaobject and a runtime class metaobject, which control
the behavior of that instance.
The runtime
metaobject is created for every (base-level) instance but the
runtime class metaobject is created for every (base-level) class.
Metaobject is the root class of the runtime
metaobject and ClassMetaobject is the root class
of the runtime class metaobject.
This package is provided as a sample implementation of the reflection mechanism with Javassist. All the programs in this package uses only the regular Javassist API; they never call any hidden methods.
The most significant class in this package is Reflection.
See the description of this class first.
