The class information is searched for a concrete class to be objectivized. An object ID that is the same as the ID of the concrete class is created; if the object ID cannot be specified, the class/method ID of a class at the head of a structure hierarchized in the form of a tree to which a related concrete class/method belongs is retrieved. The class/method ID at the head is searched for the object ID. Using the reference destination method information and the object ID as key information, a combination of the concrete class/method ID and another concrete class/method ID to which the concrete class/method ID is related is retrieved. A series of concrete classes/methods related to the class/method are extracted and displayed on a screen.;COPYRIGHT: (C)2008,JPO&INPIT
