the class CallHierarchyHandler method getIncomingCallItemsAt.

        return null;
    }

        return null;
    }
    List<CallHierarchyIncomingCall> result = new ArrayList<>();
    for (MethodWrapper call : calls) {
        Collection<CallLocation> callLocations = call.getMethodCall().getCallLocations();

                CallHierarchyItem symbol = toCallHierarchyItem(call.getMember());
                symbol.setSelectionRange(callRange);
                List<Range> ranges = toCallRanges(callLocations);
                result.add(new CallHierarchyIncomingCall(symbol, ranges));
