IntelliJ Open API usage outside of plugin development

How can I use the classes of IntelliJ Open API that perform the analysis of the Java code and its conversion to Tree Nodes? I am referring to those being used in plugin development, bu开发者_StackOverflow社区t I want to exploit them separately out of the scope of plugin development.

Have you tried to look at community editon? It's opensource and you can debug it easily. (but I'm not sure it has Open API though) http://www.jetbrains.org/display/IJOS/Download

The core of OpenAPI was recently used in the UpSource project, check it out:
