<title>ClassAdapter</title>
<para>WARNING: The classadapter model is subject to change without notice.
It is currently under developement as issues with AOP integration and using
the Microcontainer in more constrained environments are investigated.</para>
<para>The class adapter abstraction provides a mechanism to override a class
or a specific instance of a class in a given context.</para>

<title>Aims</title>
<section>
<title>AOP Integration</title>
<para>The main of the classadapter is to provide an integration point
for AOP and the microcontainer. It represents a class instance before it
is constructed or maybe even before the class has been deployed. AOP can
override the joinpoints to add extra work during construction.</para>
</section>
<section>
<title>Overridding annotations</title>
<para>The microcontainer allows annotations to be overridden on a
specific bean deployment. These are passed to AOP.</para>
</section>
<section>
<title>Obtaining AOP dependencies</title>
<para>The microcontainer uses the classadapter to learn what
cross-cutting AOP dependencies are required before any attempt is made
to construct the object.</para>
