<div class="block">Runtime Behavioral Reflection.
<p>(also recently known as interceptors or AOP?)
<p>This package enables a metaobject to trap method calls and field
accesses on a regular Java object. It provides a class
<code>Reflection</code>, which is a main module for implementing
runtime behavioral reflection.
It also provides
a class <code>Loader</code> and <code>Compiler</code>
as utilities for dynamically or statically
translating a regular class into a reflective class.
<p>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.
<code>Metaobject</code> is the root class of the runtime
metaobject and <code>ClassMetaobject</code> is the root class
of the runtime class metaobject.
<p>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.
<p>The most significant class in this package is <code>Reflection</code>.
See the description of this class first.</div>
