Class Method Details

.method_missing(name, options = {}) ⇒ Object

methods called to Grab are not really methods, they’re ghost methods. If method_missing cannot identify the number and the factory to be created it will pass this up the chain to Object. @name is the method name called (symbol) and options is the hash of options passed to the method.
