Bug 178045 – Web Inspector: replace TypeVerifier with subclasses of WI.Collection

• Component: Web Inspector
• Status: RESOLVED FIXED

[Devin Rousso]

Instead of using TypeVerifiers as distinguishers between different types of WI.Collection, we can create subclasses that allow for greater distinction between usages of WI.Collection.  This will mainly be used to make determining the placeholder text for WI.CollectionContentView simpler.

What was the reason for removing this? This delay shouldn't be that perceptible, and prevents flicker when collection items are added right after the ContentView is shown (which is typical when viewing canvases).

I was seeing a noticeable delay before the text appeared, such as viewing resource type folders on <https://www.apple.com> (like Fonts or Scripts).  I wasn't seeing any flickering elsewhere, but I haven't tested extensively.

This is better, but it still seems more complicated than necessary. If you are going to go all the way to subclassing, then each subclass should override objectHasRequiredType(o) rather than passing in a predicate function to the constructor. I don't see any reason why the predicate needs to be dynamically bound at construction time since it never seems to vary for a particular subclass.

r=me please wait for Mac EWS

If this is required to be overridden, then please 

throw WI.NotImplementedError.subclassMustOverride();

> Source/WebInspectorUI/UserInterface/Views/CollectionContentView.js:57
>              return WI.UIString("Shader Programs");

I wouldn't be sad if you made this a displayName() that must be overridden, but I won't hold up this patch for it either.

Is this leftover from another patch? It seems unrelated,

Yeah, I forgot to update localizedStrings.js when I removed the experimental Canvas settings.  Sorry.
