Eiffel Inheritance

• The parent of a class is specified with the inherit clause

• Feature clauses specify access control to the entities defined in them

• Without a modifier, the entities in a feature clause are visible to both subclasses and clients

• With the name of the class as a modifier, entities are hidden from clients but are visible to subclasses

• With the none modifier, entities are hidden from both clients and subclasses

• Inherited features can be hidden from subclasses with undefine

• Abstract classes can be defined by including the deferred modifier on the class definition
