This chapter describes various important improvements to the object oriented model for Ada 2005.
First an alternative more traditional prefixed notation for calling operations has been introduced. A major improvement is that Java-like interfaces are introduced thereby permitting simple multiple inheritance; null procedures have also been introduced as a category of operation. Greater general flexibility is provided by allowing type extension at a more nested level than that of the parent.
There are also explicit features for overcoming nasty bugs which arise from confusion between overloading and overriding.
