public static interface EntryCompletion.Match

The callback invoked when a EntryCompletion wants to ask if a given row in the TreeModel should be in the completion list. Generally, when you will receive the callback you will reach into the source's model and query a column by which you will determine whether or not to include this row. It allows you to a create a more complex completion behavior into the EntryCompletion.Match callback. The behavior of a default EntryCompletion can be written like that:

 final DataColumnString column;
 final EntryCompletion completion;
 
 ...
 
 completion.setMatchCallback(new EntryCompletion.Match() {
     public boolean onMatch(EntryCompletion source, String key, TreeIter iter) {
         final TreeModel model;
         final String text;
 
         model = source.getModel();
         text = model.getValue(iter, column);
 
         return text.startsWith(key);
     }
 });
 

If you are researching the GTK API documentation, see (*GtkEntryCompletionMatchFunc). Creating and invoking this "match" signal is how java-gnome has implemented the function pointer expected by gtk_entry_completion_set_match_func().
