Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args) ⇒ Object

Instance Method Details

#call_default_extension(method, *args) ⇒ Object

This method is explicitly called by the standard SpecTools object methods.

Calls call_extension with the method sent.

If SpecTools::Config.default_access_method is not set, SpecTools::NoAccessMethodError is raised.

def call_default_extension(method,*args)
	if SpecTools::Config.default_access_method != nil
		call_extension(method,*args)
	else
		raise SpecTools::NoAccessMethodError, 'In order to use this method, you must define Config::default_access_method'
	end
end

#call_extension(method, *args) ⇒ Object

This method allows extension developers to extend SpecTools without having to redefine stock methods. call_extension is usually invoked through method_missing or call_default_extension. It takes a method (in symbol form) and appends the prefix defined in SpecTools::Config.default_access_method . Example:

call_extension(:get_attr,*args)

if SpecTools::Config.default_access_method is set to :access, call_extension will attempt call access_call_extension(*args) on itself, if the method is available. If the method does not exist, NoMethodError is raised.
