COM interfaces have several facets. First, an interface is a deferred, or an abstract, class. This means that an interface is a specification of a type. Second, an interface pointer represents a COM object, which is callable by a client application. An object can expose several interfaces, or represent several types.
COM interfaces have several facets. First, an interface is a deferred class ("abstract class" in C++ terms). This means that an interface is a specification of a type.

==ECOM_INTERFACE==
For each interface listed in a type library, the EiffelCOM wizard generates a deferred class and two effective classes: a proxy of an interface pointer, or a client side class, and a stub of an interface pointer, or a server side class. The deferred interface class inherits from [[ref:libraries/com/reference/ecom_interface_chart|<eiffel>ECOM_INTERFACE</eiffel>]] and has a deferred feature per each interface function. Both effective classes, or implemented interfaces, inherit from the deferred class and implement its functions. The functions of the interface proxy calls the underlying C layer, which in turn calls the COM component while the functions of the interface stub implement the component functionality.
