Parent: | StandardError |
Registers any subclasses with status codes for easy lookup by set_status in Merb::Controller.
Inheritance ensures this method gets inherited by any subclasses, so it goes all the way down the chain of inheritance.
subclass<Merb::ControllerExceptions::Base>: | The Exception class that is inheriting from Merb::ControllerExceptions::Base |
:api: public
# File merb-core/lib/merb-core/controller/exceptions.rb, line 220 220: def inherited(subclass) 221: # don't set the constant yet - any class methods will be called after self.inherited 222: # unless self.status = ... is set explicitly, the status code will be inherited 223: register_status_code(subclass, self.status) if self.status? 224: end
Get the actual status-code for an Exception class.
As usual, this can come from a constant upwards in the inheritance chain.
Fixnum: | The status code of this exception. |
:api: public
# File merb-core/lib/merb-core/controller/exceptions.rb, line 174 174: def status 175: const_get(:STATUS) rescue 0 176: end
Set the actual status-code for an Exception class.
If possible, set the STATUS constant, and update any previously registered (inherited) status-code.
num<~to_i>: | The status code |
(Integer, nil): | The status set on this exception, or nil if a status was already set. |

Register the status-code for an Exception class.
