Instance Method Details

#find(x) ⇒ Object

Converts the supplied value to an instance of the specified class (if it isn’t already one). For example, within the Source object you could find the Bloomberg object one of two ways:

Rupee::Source.find :bloomberg
Rupee::Source.find Rupee::Source::BLOOMBERG

This allows the user more flexibility, as specifying the full path to the BLOOMBERG constant is no longer necessary
