### Question:
ComparableSetBinding extends ComparableBinding { public static ArrayByteIterable comparableSetToEntry(@NotNull final ComparableSet object) { return BINDING.objectToEntry(object); } private  ComparableSetBinding(); @Override ComparableSet readObject(@NotNull final ByteArrayInputStream stream); @Override void writeObject(@NotNull final LightOutputStream output, @NotNull final Comparable object); static ComparableSet entryToComparableSet(@NotNull final ByteIterable entry); static ArrayByteIterable comparableSetToEntry(@NotNull final ComparableSet object); static final ComparableSetBinding BINDING; }### Answer:
@Test(expected = ExodusException.class) public void empty() { ComparableSetBinding.comparableSetToEntry(new ComparableSet()); }
