## Notes

- Archive of my senior thesis in 1998

- Platform: GNU C/C++ 2.7.2.1 on Linux 2.0.29 (32bit)

- Not working on current platforms

## Sample Code

```cpp

// Declarations

PersistentStorage *ps; // the persistent storage 

PersistentPointer pp;  // the persistent pointer

PersistentObject *obj; // the reference pointer

pp = ps->allocate(sizeof(PersistentObject)); // Allocate

  // Grab and Instantiate

  obj = new(pp.grab()) PersistentObject(parameters, ...); 

    obj->manipulate(parameters, ...); // Manipulate

  pp.release(); // Release 

  obj = 0; // Invalidate the reference pointer

  obj = pp.grabReadOnly(); // Read-only-Grab

    obj->reference(parameters, ...); // Reference

  pp.releaseReadOnly(); // Read-only-Release

  obj = 0; // Invalidate the reference pointer

  obj = pp.grab(); // Grab

  obj->~PersistentObject(); // Destruct

ps->destroy(pp); // Destroy (also Release)

ps->synchronize(); // Synchronize

```
