Module: Seatbelt::Ghost

Defined in:
lib/seatbelt/ghost.rb

Overview

Public: Handles calling and defining of API methods.

Any class that should acts like a API Class have to include this module.

class Flight

include Seatbelt::Ghost

api_method  :estimated_flight_time

api_method  :find_flights,
            :scope => :class

end

flight = Flight.new flight.estimated_flight_time(:to => “London”) Flight.find_flights(:to => “London”, :from => “Frankfurt”)

Defined Under Namespace

Modules: ClassMethods, EigenmethodStore

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_name, *args, &block) ⇒ Object

Public: Calls a API instance method. If the method isn’t defined or found in the class lookup table a Seatbelt::Errors::NoMethodError is raised.

If method is defined it passes the calling responsibility to the core Callee module.

method_name - the called methods name *args - the methods argument list &block - the methods block (this is optional)

Returns the evaluted method value.
