Can you please upload patches with full context? (use arc ideally, or git -U99999)

[lipracer]

Difference patch with full context.

Your commit title is confusing to me, you wrote "remove rundant define of getElementType" but wouldn't it be more accurate to say "Add explicit using getElementType for base class to disambiguate between multiple implementations" or something like that?
