1136065 - GetRangeCount() and RangeCount() do the same thing in Selection.h

Status: RESOLVED FIXED

(Core :: DOM: Selection, defect)

Description

[Ting-Yu Lin [:TYLin] (UTC-8)]

We have two identical functions GetRangeCount() [1] and RangeCount() [2] in Selection.h.  Besides, we already have another GetRangeCount(int32_t* aRangeCount) [3] which implements nsISelection.idl.

To avoid confusion, I think we should keep RangeCount() and eliminate the zero argument GetRangeCount().

Also, the WebIDL bindings call RangeCount(), if I'm not mistaken.

We replace GetRangeCount() with the identical function RangeCount() to
avoid any confusion.

It is better to cast the RangeCount() to int32_t which is the same type as aSelectionNum.
