Abstract
A method and apparatus for reclaiming memory space allocated to data structures comprising data objects linked by identifying pointers. The memory allocated to data objects is reclaimed using two systems. In the first system ( ), the data structures are traversed to identify those objects to which no references are made by the pointers of other objects, and the memory allocated to those objects to which no references are made is reclaimed. In the second system ( ), objects which are not descendants of root objects are determined and the memory allocated to those objects is reclaimed. Cycles of the first system are interleaved with cycles of the second system.
