1. In a distributed object application builder apparatus having a graphical user interface in which parts having plugs and sockets are interconnected to define distributed object application programs, said parts corresponding to components and representing distributed objects, a computer-implemented method of determining the plugs of a first part using said graphical user interface, said method comprising the steps of:

  • identifying the first part by performing a selection action on the first part, said first part being represented by a graphical representation;

    retrieving an interface for a first component that corresponds to the first part;

    determining at least one attribute from the retrieved interface, each determined attribute having an associated attribute type;

    determining at least one operation from the retrieved interface, each determined operation having an associated operation type;

    retrieving a factory argument list from a factory method associated with said first component;

    identifying at least one input argument from the retrieved factory argument list, each identified input argument having an associated input argument type; and

    indicating visually that said at least one attribute, said at least one operation and said at least one input argument are the determined plugs of the first part.
