This is the only method that a subclass of ExchangeRate needs to implement. This is a good example to follow. 

     # File lib/van/units/currency.rb, line 129
129:         def get_rate
130:           data[@curr]
131:         end

Private Instance Methods

data() click to toggle source 
     # File lib/van/units/currency.rb, line 135
135:         def data
136:           @@data ||= eval(File.read(File.join(Units::Config::CONFIGDIR, 'xmethods', 'cached.rb')))
137:         end
