ICompilationUnit persistence [message #211505]

I'm writing an eclipse plug-in (an screen design editor) and I'm a
relative newbie. This can be a dangerous combination. At one point in my
code, I have a reference to an ICompilationUnit. I would like to find an
easy way to save some data about this unit into my proprietary XML. It
looks like I need to perhaps save the project name and some path
information. Then when the file is reopened, I'd like to again have
access to the same ICompilationUnit.

So something like:

<controller>
<controllerProject>
FooBar
</controllerProject>
<controllerPath>
com.expd.arch.TestController.java
</controllerPath>
</controller>

Can someone point me to the correct API calls to make this happen?

You could use IJavaElement#getHandleIdentifier() to save the reference and
JavaCore#create(String) to re-create the ICompilationUnit.
