Abstract: A method and apparatus for connecting two components is disclosed. A visual construction simplification mechanism, as part of the apparatus, is designed with intelligence that allows it to correctly configure and interconnect the two components. The invention reduces the real and visual complexity of a program by requiring only a single bootstrap connection to be established between the components. Once the initial connection is made, the visual construction simplification mechanism can make additional connections that allow the two objects two function and interoperate. Introspection is a process used to find a component's interface and identity. The visuals construction simplification mechanism looks at the interface of one component and figures out what the identity of the component is using the process of introspection. Introspection is a generic term for the ability of any component to look at the details of another component.
