HandleRegistries are like Registries, in that they watch for the death of
|
|
|
39 |
a registered object. However, they send a self-change notification, passing the registered
|
|
|
40 |
handle as argument, instead of creating a shallow copy and letting it do the finalization.
|
|
|
41 |
Use Registry for objects which know themself how to clean up;
|
|
|
42 |
use HandleRegistry, if someone else does the cleanup.
