My situation is this: I need to parse the file currently open in the java

if I can get the IFile object representing the .java file I am editing, I
think everything will work. However, I have been unable to find out how
to get this IFile (or something equivilant). Does anyone have suggestions
about how I should go about this?
Thanks,
Dave

OK, I get that much. However, I'm still having trouble getting hold of
the IEditorPart. The two possibilites I've found are:
BasicTextEditorActionContributor.getActiveEditorPart()
and
IWorkbenchPage.getActiveEditor()
The trouble is, I'm still not sure how to get a hold of the
BasicTextEditorActionContributor or IWorkbenchPage objects to do these
operations on.
I think part of my problem is that I'm still not really sure about how to
get at and use the Workspace, and all the related parts. I've looked
through the API and it doesn't seem to be much help. Any suggestions
about how I should proceed, or where to look for more information?
Thanks,
Dave

Perhaps this is the wrong question but... why would you want to do all this
parsing yourself? The JDT provides a real handy parser and an underlying
model. My article, "Extend Eclipse's Java Development Tools"
( http://www-106.ibm.com/developerworks/opensource/library/os- ecjdt/) gives
you a flavor for what's possible (more detail in Chapter 26 of our book).
More directly to your question, you can get the editor's input
(IEditorInput) and from there its underlying IFile, source, compilation
unit, whatever.
I suggest you consider going the JDT route because the end result will
integrate much better. To give you just an example of what might be an
issue otherwise: Consider if the editor content is modified but not yet
saved to disk. If you go the IFile route, you'll be parsing a backlevel
copy of the code. The JDT handles all the in-memory and disk
synchronization. It's a lot to learn in one sitting but worth your time.
