Bug 112279 – Small ResourceLoader cleanups

• Component: Page Loading
• Status: RESOLVED FIXED

[Brady Eidson]

Two small ResourceLoader cleanups I noticed were worthwhile while working on a larger patch:

1 - Classes that derive from ResourceLoader should use OVERRIDE on the virtual methods they override.  Important for catching mistakes in future refactoring.
2 - the "bool allAtOnce" flag is mysterious when reading code that has just "true" or "false", so change it to an enum that encapsulates what it means.

Are more types going in this header? If not, it should be named "DataPayloadType.h".

"is expected" is a little strong in this context. DataPayloadWholeResource is an optimization that happens sometimes. We don't have a specific expectation about how often. I would say, "DataPayloadWholeResource indicates that the buffer points...".

I would use "indicates" here as well.

At least one other will be in the extremely near future.

Done and done.
