ABSTRACT:
A garbage collector that employs the train algorithm divides object classes into a number of class groups, which are considered to have different ranks. The class group having the lowest rank, for example, may include only classes whose instances contain no references. The group of the next-higher rank may consist of classes whose instances include references only to objects that are instances of final classes whose instances include no references. The highest-rank group may include all other classes. Car sections are associated with the class groups and contain only instances of classes belonging to the class groups with which they are associated. Within each train, each car associated with a class group of a higher-rank is placed earlier in the collection order than is a car associated with a lower-rank class group.
