Class Method Details

.sideload_inheritance_chain(obj, options) ⇒ Object

Side loads the class, and its super classes that respond to ‘.source_path`.

Set the ‘abstract_class` class variable to true in any class, and it will not be side loaded.

If the class responds to ‘.sideload`, it will be called instead of the regular side loading. You can use this to customise what is side loaded.
