Bug 149923 – Rationalize JSXXConstructor class definition generated from WebIDL

• Component: WebCore JavaScript
• Status: RESOLVED FIXED

[youenn fablet]

Depending on the WebIDL and options, the JSXXConstructor generated class declaration is changing.
It may be useful to rationalize this so that it can be later templated, which would simplify the binding generator work.

I don’t understand the use of ".=" instead of "=" here.

I don’t think comments like this one are useful when the entire body of #if/#else/#endif is only 6 lines long. Especially in generated code that people should typically not be reading.

Right.
Let's also remove $overloadedIndexString at the same time.

The #else case causes build failure, because there is no cell named variable/argument here.

I'm going to fix this in bug149956.
