Abstract

Methods, software, and apparatus for analyzing a software component within an application builder tool are disclosed. The present invention relates, in one aspect, to a method for analyzing a software component that can be visually moved within an application builder tool running on a computer. The method involves obtaining the software component to be analyzed and determining if the software component has an associated information class. When it is determined that the software component has an associated information class, the information class is queried about information stored within the information class, otherwise automatic analysis using design patterns is applied to analyze the class. In one embodiment, the information stored within the information class relates to methods, properties, and/or events.
