Abstract
The method of the present invention is useful in a computer system having a user interface, a memory, a repository and a database. The method is a repository program executed by the computer system for locating a versioned object within a history of objects stored in the repository. The method comprises the steps of declaring a variable workObject; if the desired variant is equal to the variant of object on which the requesting step is called, setting the workObject to said object; if the desired variant is not equal to the variant of object on which the requesting step is called, setting the workObject to a root object; if the workObject variable is null, pushing a noSuchVariant error onto a notification stack and exiting the method; determining direction for searching the version tree using the desired version and the version of workObject; if the workObject is visible, returning said workObject as the desired version; if the workObject is not visible and the desired version is equal to zero, determining if the workObject has previous versions; if the workObject has no previous versions, returning a null object.
