ABSTRACT:
Apparatus, methods, systems, and computer program products are disclosed that use a link to access nodes in a generational garbage collected heap. The creation area of the heap is associated with a validation variable that is dependent on the number of scavenge operations performed on the creation area. The link comprises the value of the validation variable when the node was allocated and the index of the created node within the creation area. When the node is copied from the creation area an entry is made in a link-to-pointer translation table. Accesses to the node using the link succeed regardless of whether the node is in the creation area. Thus, not all references to the node need to be updated when the node is copied from the creation area allowing the copying process to be interrupted when resolving links to the copied node.
