Method and apparatus for managing persistent data objects between persistent storage and memory. A plurality of the objects include one or more pointer values that reference other ones of the objects. Persistent storage pointer values in an object are swizzled to memory pointer values when the object is transferred from persistent storage to memory. The memory pointer values in an object to persistent storage pointer values are unswizzled when the object is transferred from memory to persistent storage. In generating a persistent storage address from a persistent storage pointer value, the persistent storage pointer value is multiplied by a selected multiplier.
