Hi,

I've a quick query concerning an org.eclipse.jface.viewers.ViewerSorter.
I want to ensure that there are no duplicate entries in my TableViewer.
So, when the compare() method of the ViewerSorter is called and 0 is
returned (i.e. first element is equal to the second element), I want to be
able to identify this occurance.

Then I can choose not to add this duplicate item. I add items to the
TableViewer using the add(Object element) method.

Thanks,
Shane

Well, AFAIK the sorter is called *after* you have inserted the elements.
I think filtering could only be done before inserting the data (maybe at
content provider level).
