Re: [jdt-dev] Displaying only certain types

[Timothy Halloran <thallora@xxxxxxxxxxxxxxxxx>]

Are you talking about the actual class of the ICompilationUnit or the
public class/interface that is within the source code file the
ICompilationUnit refers too??

I suspect the latter, really this is complicated by files declaring more
than a single class (or interface) and nested classes.  In the most
general case, you probably need to generate the CompilationUnit and go
through the ASTNodes, but try this:

Say your ICompilationUnit is javaFile:

   IType[] declaredTypes = javaFile.getAllTypes();

Now you have the types declared in the file (look at the JavaDoc for
IType) and can examine the superclass or interface hierarchy for each of
the IType's you found in the ICompilationUnit via getSuperclassName() or
getSuperInterfaceNames() -- the problem is these may not be qualified to
the level you might expect (read the JavaDoc carefully here).

If you care about nested classes you need to go through each IType's
getTypes() list of IType(s).

I've never tried this..I usually use CompilationUnit(s) with binding,
but then the software actually has to build...Good luck
