Refactor WebGLArray types to share more code

• Component: WebGL
• Status: RESOLVED FIXED

[Kenneth Russell]

At the WebKit meeting this past week Darin Adler pointed out that there are code sharing opportunities between the various WebGL<T>Array types. Some of these have been addressed with a recent refactoring to the range checking code, but more refactorings would be possible with a template base class between WebGLArray and the concrete types.

Patch

From the ChangeLog:

Refactored WebGLArray types for maximal code sharing. Added WebGLTypedArrayBase and WebGLIntegralTypedArrayBase template superclasses. Changed overridden virtuals to have minimal visibility (private instead of public). Fixed const correctness of a few methods. There are no changes to the public APIs of the WebGLArray classes; the JavaScript bindings are unchanged.

No new tests; existing tests cover this functionality. Ran all WebGL layout tests in Safari and Chromium on Mac OS X.

It would be great to either annotate each change or just remove this huge laundry list of files from the ChangeLog -- you already have refactoring described.

WebCore/html/canvas/WebGLTypedArrayBase.h:85
 +          return adoptRef(new Subclass(buf, byteOffset, length));
Awesome.

Thanks for the feedback. I'm reluctant to remove the list of modified files / methods because other recent ChangeLog entries do the same thing, so I'm going to leave this as is.
