Bug 224616 – Refactor inline functions out of HashMapImpl.h into HashMapImplInlines.h.

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Mark Lam]

Also do the same for clients of HashMapImpl that require similar refactoring.  This fixes the #include of JSCJSValueInlines.h in HashMapImpl.h, as well as makes it easier to use other inline functions from other classes in the implementation of HashMapImpl's inline functions in the future.

Never noticed when this first was introduced: Seems unfortunate that WTF has WTF::HashMap and JavaScriptCore has unrelated JSC::HashMapImpl. Might be worth thinking about future name changes to clarify the relationship/distinction

Thanks for the review.  Landed in r276039: <http://trac.webkit.org/r276039>.

I think we could simply remove the declarations of these functions from HashMapImpl.h. If they're needed, better include HashMapImplInlines.h, yes?

Looking at this again, I think these 2 functions are only used by clients in HeapMapImplInlines.h.  So, yes, I think we can simply remove these declarations from HashMapImpl.h.
