1. A mechanism for providing a client access to implementation objects in a multi-language computing environment supporting interface composition through inheritance and implementation inheritance from common base classes, said mechanism comprising:

  • a pure interface base class adapted for generating a hierarchy of pure interface classes containing only method implementations and instance data common to proxies and implementations;

    a means for directly accessing an implementation object in response to a user access request on a local same-language implementation object, said implementation inheriting from the pure interface class hierarchy; and

    a means for generating a first proxy object in response to a user access request on a local cross-language implementation object, said first proxy object inheriting from the pure interface class hierarchy;

    wherein said mechanism provides said client with apparently transparent access to said implementation objects.
