Eclipse + UML + Javadoc

Hey Eclipse Java Programmers.

I want to automatically put UML representations of my stuff in the Javadoc, just like yDoc does.
Is there anything like it as an Eclipse plug-in? Thanks.

HAY why hasnt some invented some like mega meta language that just lets you switch between all languages right there in the code...it would be aewsome.. and would have super intelligent fast marshalling of types between them
