A class is a description of a set of objects that share the same attributes,
operations, methods, relationships, and semantics. A class may use a set
of interfaces to specify collections of operations it provides to its environment.
In the metamodel, a Class describes a set of objects sharing a collection
of Features that are common to the set of objects.
The purpose of
a Class is to declare a collection of Features that fully describe the
structure and behavior of objects. Some Classes may not be directly instantiated.
These Classes are said to be abstract and exist only for other Classes
to inherit and reuse the Features declared by them. No object may be a
direct instance of an abstract Class, although an object may be an indirect
instance of one through a subclass that is non-abstract.
A Class
acts as the namespace for various kinds of contained elements defined within
its scope, including classes, interfaces and associations (note that this
is purely a scoping construction and does not imply anything about aggregation).
The contained classes can be used as ordinary classes in the container
class. If a class inherits another class, the contents of the ancestor
are available to its descendents if the visibility of an element is public
or protected; however, if the visibility is private, then the element is
not visible and therefore not available in the descendant.
