Instance Method Details

#after(*methods, &block) ⇒ Object

A method to add a callback to a method or a list of methods to be executed after the original method was executed. E.g.:

MyClass.after :some_method do awesome_stuff end

It can only take a list of methods after which a block should be executed:

MyClass.after :method1, :method2, :method3 do puts 'jay!' end

The list might also be an Array.

def after(*methods, &block)
  _after_do_define_callback(:after, methods, block)
end

#before(*methods, &block) ⇒ Object

This method works much like .after - just that the blocks are executed before the method is called.
