Ada & Object-Oriented Methodologies

Ada & Object-Oriented Methodologies

[Francisco San Martin Roman]

	I'd never used Ada, and I need to know : How can I do to implement
object-oriented concepts (modularity, hierarchy, encapsulation, abstraction) if
any in Ada programming? I'll really appreciate your help.

This is like asking "Is the Pope Catholic?"

Almost any Ada text will cover object-oriented methodologies implemented
in Ada.  If you heard that Ada could not implement OOD, it might be in
reference to Ada 83 not handling inheritance. If OOD is possible without
inheritance or if Ada 83 can emulate inheritance are both moot questions
since, Ada 95 will include inheritance.

Ada 83 fully supports modularity, encapsulation, and abstraction.
The constructs of most relevance here are the package and the private type.

In addition to the above, Ada 95 also fully supports type hierarchies 
(Ada 83 supports them in a more restricted fashion).  The constructs 
relevant here are type extension and class-wide types.

The Ada 95 Rationale is a good place to start (sw-eng.falls-church.va.us,
directory public/adaic/docs/standard/95lrm_rat/v6.0).
