Bug 101564 – [EFL][WK2] Make classes for client use WebContext instead of WKContext

• Component: WebKit EFL
• Status: RESOLVED FIXED

[Jinwoo Song]

ewk_context has been refactored to use WebContext instead of WKContext in r133844. So client classes also should changed to use WebContext.

smart pointer classes have -> operator overloaded!

m_context->batteryManagerProxy()

BTW, you should reconsider your patch after https://bugs.webkit.org/show_bug.cgi?id=101565 lands

after PassRefPtr has been assigned to smth you can never use it again, and this problem is pretty hard to see on review since the code which needs modification might not not in the patch.

It's a good habit to run tests or mini browser at least before uploading a patch.

My bad. I usually run API test before submitting patch, but I did not run in this time as the patch was rebased many times. I should have tested the API test and Minibrowser and I'll double check next time. I'm sorry for bothering you.
