Class: Geokit::GeoLoc
Overview
This class encapsulates the result of a geocoding call. It’s primary purpose is to homogenize the results of multiple geocoding providers. It also provides some additional functionality, such as the “full address” method for geocoders that do not provide a full address in their results (for example, Yahoo), and the “is_us” method.
Some geocoders can return multple results. Geoloc can capture multiple results through its “all” method.
For the geocoder setting the results, it would look something like this:
geo=GeoLoc.new(first_result)
geo.all.push(second_result)
geo.all.push(third_result)
Then, for the user of the result:
puts geo.full_address # just like usual
puts geo.all.size => 3 # there's three results total
puts geo.all.first # all is just an array or additional geolocs,
so do what you want with it
