How to determine if IVersionable is a file or a directory?

Jazzers,

with a handle in IVersionable, what is a fast way to determine in java code whether this IVersionable is a directory or a file?
Underlying reason: for a change set I want to determine whether it contains actual file changes or "just" added / removed directories.

Best,
Arne

I think you have to resolve it and then check the versionable for type of IFolder.

if its NOT an IFolder then it must be a file.

It could also be a symbolic link in case it's required to detect files. It would be best to check specifically for the type that you want.

I didn't see an IFile (or symbolic link) type in the (5.0) javadoc.

IFileItem isn't in the javadoc was the only reason I didn't recommend it.

Thanks, everybody.
Actually I found IFolderHandle and now trying this:
                 
            boolean result = ChangeSetFilter.IS_NOT_FILTERED;
            List <IChange> changeList = changeSet.changes();
if (changeList.isEmpty()) {
result = ChangeSetFilter.IS_FILTERED;
return result;
}
            for (IChange change : changeList) {
                if(! (change.item() instanceof IFolderHandle)) {
                    result = ChangeSetFilter.IS_FILTERED; 
                    return result;
                }
            }

(hopefully) sneakily getting around having to resolve all change set handles.
Will update this if this is *not* working and post alternative.
