[xmlvm-users] CoreLocation and static double numbers

[Panayotis K. <pan...@pa...>]

Hello all!

I am implementing CoreLocation library (actually it is ready and working) but I'd like your opinion about one thing.

Here
http://developer.apple.com/library/ios/documentation/CoreLocation/Reference/CLLocation_Class/CLLocation/CLLocation.html#//apple_ref/doc/uid/TP40007126-CH3-SW27

is a list of constant double values. These values define the accuracy of the location, and I found that they have meaningful values (i.e kCLLocationAccuracyNearestTenMeters is 10, kCLLocationAccuracyKilometer is 1000 etc).

I have created a class containing these static values, but since these are double values and not integers, it is always possible that equality might not work as expected.

I tried to check every one of them with something like 
java_value == kCLLocationAccuracy_value
and they all seem OK.




On the other hand, it might be possible to create a wrapper method that returns this value, i.e. something like

public static double Kilometer () { .. }

in java and

+ (double) Kilometer__ {   return kCLLocationAccuracyKilometer; }

in obj-c, and use the static methods instead.
This might be safer but it is slower.

Since the "constant variable" solution works fine, I'd rather prefer that solution.
What do you think?
