Class Method Details

.prepend_features(othermod) ⇒ Object

The semantics of prepend are such that the super method becomes wholly inaccessible. So if we override a method (like, say, initialize), we have to stash the original method implementation if we ever want to find out its file and line number.

Instance Method Details

#initialize(*args, **kwargs, &block) ⇒ Object

Wrap the initialize method to automatically call check_ivars This method handles the initialization process, including:

  1. Processing manifest declarations before calling super

  2. Checking instance variables for validity
