Not quite.  In C++, a class is both a unit of encapsulation (a module)
and a data type.  Ada separates these concepts.  A package is a
module, but it's not a data type, (though you can declare data types
within it); it's similar to a C++ namespace.  A record type is like a
C++ struct; a tagged type is like a class.

The closest Ada equivalent to a class is probably a package declaring
a single tagged type and the operations on it, but Ada packages
provide more flexibility.
