698566 - Expose JSPropertyName in JSAPI

Status: NEW

(Core :: JavaScript Engine, defect)

Description

[Jeff Walden [:Waldo]]

JS_GetElement and friends do fast stuff for uint32 properties.  We need similar fast paths for non-uint32 properties known not to be special.  Pretty much every place where we look up a property using a char* could use this if it were available.

Luke and I were talking about how it'd be nice if the string hierarchy were exposed -- to some extent (JSShortAtom or whatever shouldn't be exposed, nor should various other internal-use-only classes) -- in the public API.  It'd be the usual shadow-class thing and all, with JSString being a class a single word in size, JSLinearString being a subtype of it, JSFixedString a subtype of that, JSAtom under that, JSPropertyName under that.  Each class could have member methods that did the cast to the internal type and forward the op, or worked on shadow fields in the shadow class, or whatever.  Probably that would want to happen before this.
