IInterfaceDeclaration
Declare and check the interfaces of objects
The functions defined in this interface are used to declare the
interfaces that objects provide and to query the interfaces that have
been declared.
Interfaces can be declared for objects in two ways:
- Interfaces are declared for instances of the object's class
- Interfaces are declared for the object directly.
The interfaces declared for an object are, therefore, the union of
interfaces declared for the object directly and the interfaces
declared for instances of the object's class.
Note that we say that a class implements the interfaces provided
by it's instances. An instance can also provide interfaces
directly. The interfaces provided by an object are the union of
the interfaces provided directly and the interfaces implemented by
the class.

providedBy(self,
ob)
Is the interface implemented by an object |
