Is there any Java library, that can help in building AST from the specified java source file and vice versa (generate code from the ASTree object)? I need something like this, but with an API, allowing to access the generated tree programmatically.
Everything's already available within the Eclipse core.
Here's a page with a small example of how to use org.eclipse.jdt.core.dom.ASTParser to create your desired AST datastructure.
