[news.eclipse.tools.jdt] How to get context information

[mmooty.gam@xxxxxxxxx (mathew mooty)]

I am trying to get the class of an identifier directly before the 
invocation offset of the completion. For example,

File newFile = new File("fileName");
String stuff = newFile.|    //the '|' is the invocation offset

OR

File newFile = new File("fileName");
newFile.|    //the '|' is the invocation offset

In this case, I want to know about the token "newFile". I would like to 
know it's qualified type, at the very least. I have looked in the 
CompletionContext class, the JavaContentAssistInvocationContext class, and 
in the AST API, but I cannot find a way to get that information. The AST's 
handling of incomplete statements is such that it merges them with the 
following statement, resulting in this code:

File newFile = new File("fileName");
String stuff = newFile.
otherVariable = someValue; 

becoming

String stuff = newFile.otherVariable = someValue;

in the AST. 

If someone could please help me out on finding the value of newFile within 
the AST or within JDT's context API, that'd be wonderful.

Thanks,
