| managed_object () | |
| managed_object (contents *&_object) | |
| Pass a pointer of the object to be stored. | |
| managed_object (const managed_object &_rhs) | |
| Moves the contained object in _rhs into a new managed_object. | |
| managed_object & | operator= (const managed_object &rhs) |
| Moves the contents of _rhs into this object. | |
| virtual | ~managed_object () |
| Releases the object contained here. | |
| bool | operator== (const managed_object &_compare) const |
| managed_object< contents > * | new_reference () |
| Return a new reference to the managed object class. | |
| contents * | access () |
| access the originally stored object | |
| const contents * | observe () const |
| look at the originally stored object | |
Provides an object management system that allows for references to an original stored object to be obtained, and the original object is not deleted until all references are gone.

| managed_object< contents >::managed_object | ( | ) |
Having a default constructor for a managed object does not make a lot of sense, since the whole point is you are managing another object. However, there are circumstances that make it useful.
Definition at line 58 of file managed_object.cpp.
| managed_object< contents >::managed_object | ( | contents *& | _object | ) |
Pass a pointer of the object to be stored.
The managed_object class takes control of the pointer and sets the reference null before returning. The original object is wrapped in the ObjectStorer class so that the number of references can be counted.

References NULL.
| managed_object< contents >::managed_object | ( | const managed_object< contents > & | _rhs | ) |
Moves the contained object in _rhs into a new managed_object.
Definition at line 68 of file managed_object.cpp.
| managed_object< contents >::~managed_object | ( | ) | [virtual] |
Releases the object contained here.
Doesn't delete the actual object, just tells the storer to decrement its reference count. When all references are gone the original object will be deleted.

References NULL.
| managed_object< contents > & managed_object< contents >::operator= | ( | const managed_object< contents > & | rhs | ) |
Moves the contents of _rhs into this object.
Causes this object storer to have its reference count decremented, then the object storer pointer from the rhs is copied and its reference count is incremented.

References NULL, and managed_object< contents >::storer.
| bool managed_object< contents >::operator== | ( | const managed_object< contents > & | _compare | ) | const |
The equality operator for the managed_object invokes the equality operator on its stored pointer.

References NULL, and managed_object< contents >::storer.
| managed_object< contents > * managed_object< contents >::new_reference | ( | ) |
Return a new reference to the managed object class.
This uses the private constructor that simply copies the object storer pointer. We don't want to copy the actual stored object. The returned pointer must be deleted when it is finished being used. This can be achieved using the copy constructor also.
