Bug 119725 – Simplify RadioNodeList's anonymous indexed getter

• Component: DOM
• Status: RESOLVED FIXED

[Ryosuke Niwa]

Consider merging https://chromium.googlesource.com/chromium/blink/+/c06e3ea129f0a16eb4275a2c6bb9e77094bda632

Make RadioNodeList's anonymous indexed getter argument mandatory and drop
the [IsIndex] IDL extended attribute. 'optional' and [IsIndex] have no
effect on the generated code of anonymous indexed getters:
- There is no way for the caller to omit the index
- The generated code uses ObjectTemplate::SetIndexedPropertyHandler() and
the IndexedPropertyGetterCallback takes a uint32_t in argument.

There is no web-exposed behavior change, the generated bindings code is identical.

Doesn't IsIndex cause INDEX_SIZE_ERR to be thrown when the index is negative?

In theory, yes but not for anonymous indexed getters. As I said in the Changelog, the generated code is *exactly* the same. Also note that throwing an INDEX_SIZE_ERR for negative values in indexed getter would not be according to specification.
