Maintaining correctness of pointers from a managed heap to off-heap memory

Abstract:

A method of maintaining correctness of pointers from a managed heap to off-heap memory includes storing in a cache a first heap object in a managed heap that holds at least one off-heap pointer pointing to a first off-heap data structure and creating a weak reference node linked to the first heap object such that the first heap object is not kept alive by the weak reference node during garbage collection. Further disclosed are systems for maintaining correctness of pointers from a managed heap to off-heap memory.
