This is used as a finalization handle for views - in previous systems,
|
|
|
39 |
a shallowCopy of a view was responsible to destroy the underlying
|
|
|
40 |
devices view. To make the memory requirements smaller and to speed up
|
|
|
41 |
view creation a bit, this lightweight class is used now, which only
|
|
|
42 |
keeps the device handle for finalization.
