<p>PURPOSE:To refer to traffic on message lines and the hierarchical structure of an object at the same time and to make object-oriented system development efficient by repressing hierarchical structure with denotative relation by repetitive processing. CONSTITUTION:A storage means is stored with information on tree-shaped hierarchical structure as to a series of object groups and object layers are represented by repeating denotation of figures. Arrow figures a10, a20... are generated between a start point and an end point and messages i10, i20... are given to generate message lines. After the message lines are generated, the respective message lines are equally arranged, and then message identifiers are made into character strings and arranged nearby the respective message lines. After the arrangement, the respective message lines are moved to make the display screen of a display easy to see. Therefore, the hierarchical structure is represented with the denotative relation, and the start point and end point positions of message sending which is made into segments are determined in the connotative region, so neither an intersection nor an overlap is generated.</p> |
