* The CoreLocationObjects class contains the CoreLocation objects
|
|
* we'll need.
|
|
*
|
|
* Declaring them directly in CoreLocationLocationProvider
|
|
* would require Objective-C++ syntax, which would contaminate all
|
|
* files that include this header and require them to be Objective-C++
|
|
* as well.
|
|
*
|
|
* The solution then is to forward-declare CoreLocationObjects here and
|
|
* hold a pointer to it in CoreLocationLocationProvider, and only actually
|
|
* define it in CoreLocationLocationProvider.mm, thus making it safe
|
|
* for Geolocation.cpp, which is C++-only, to include this header.
