Abstract

The invention is directed to a method for distinguishing reachable objects and non-reachable objects in an object-based application in a system with a volatile memory and a non-volatile memory. The object-based application operates in the non-volatile memory on the objects, whereof at least one is a root object. Each root object is processed by writing for each object that is reachable from the root object, a positive reachability information into the volatile memory and marking those objects in the non-volatile memory as reusable memory, for which no positive reachability information is present in the volatile memory.
