摘要

Method, system and article of manufacture for creating an object oriented component having multiple bidirectional ports for use with an object oriented based applet or application. The component's ports are all first initialized to a predetermined value and thereafter polled to determine if an input has been coupled to any one of the ports. If it has not, polling continues. If an input is present, all of the component's remaining ports are set to output the same type and value as that of the input. Where appropriate, a check is made to determine if a saved state of the component exists, if it does, the component is initialized to the state type and value rather than the predetermined type and value. When the input is removed, the component ports are all reinitialized to the predetermined type and value and polling for a new input commences.
