Overview

Once a string specifier is passed into the constructer method, it’s stored and then matched against one of several patterns to determine it’s type. This type is then used to choose the output format of the specifier, when the instantiated class object is coerced back to a string.

def inspect
  "#<#{self.class} specifier=\"#{@spec}\" type=:#{@type}>"

#to_s ⇒ Object

Output the correct ‘string’ format for our specifier. The :uid and :did types have special characters prepended to their value, so that they are correctly formatted for use in a DND connection/protocol lookup command.
