Object State Viewers (OSV)
When an object is selected in the Objects pane of the main window, the registered Object State Viewer (OSV) for that object type is invoked. An OSV makes information about the selected object available via the user interface. An OSV for Atomic Actions is distributed with the standard tools. It displays information on the Abstract Records in its various lists, such as heuristic, failed, and read-only. You can write your own OSVs to display information about object types you have defined.
