System and method for displaying a recursive relationship between objects in a tree

摘要

A computer program product is provided as a system and associated method that allows the user to view a hierarchical lineage in a tree format even in the event of recursive circular relationships. The system prevents the lineage tree from being infinitely expandable truncating tree expansion when encountering a child that has previously appeared in the tree. If the user attempts to expand on an object that leads to a child already displayed in the tree, the system replaces the child's icon with one that resembles a recursive icon. The recursive icon is displayed by the system at the point of recursion, showing that an infinite, recursive relationship has occurred.
