Bug 77289 – Web Inspector: CodeGeneratorInspector.py: reimplement generated array types

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Peter Rybin]

Array type should be rendered more of a helper kind, rather than the current first class citizen kind (when it gets its name from parameter name and incapsulates more important item type).

Why not use T::ItemTraits directly?

We don't normally use Of in container type names, e.g. it's map or vector, not mapOf or VectorOf.

just struct?

why do we need to include type into method name, i.e. why not just push()?

Why do we need this wrapper?

just push()?

ditto

Does this compile?

This template type is a point where C++ specialization takes part. This class is only a default implementation.
I added a comment.

Get rid of "of"? It's cleaner? Thanks Sean! :)

Done

There is a template/specialization machinery with "T"/"RefPtr<T>" method overloading here, plus the entire code is generated. I would prefer to at least dismiss internal method overloading in favor of keeping it cleaner. So I have 2 explicitly named methods. This is not user-facing.

See above.

Yes. Why?

Extra line.

> +    for (unsigned i = 0; i < array->length(); i++) {

Please remove braces.
