preparations for lined index list in WeakArray

as long as the keys are still referenced by some |
1263 | 45 |
other (non-weak) object. |
46 |
However, once the last non-weak reference ceases to exist, |
|
47 |
the object will be automatically removed from the Weakcollection |
|
48 |
(with some delay: it will be removed after the next garbage collect). |
|
49 |
||
50 |
This class was added to support keeping track of dependents without |
|
88 | 51 |
keeping the values alive - values simply become nil when no one else |
52 |
references it. The original dependency mechanism used a regular Dictionary, |
|
53 |
which usually leads to a lot of garbage being kept due to a forgotten |
|
54 |
release. Using a WeakDictionary may be incompatible to ST-80 but is much |
|
55 |
more comfortable, since no manual release of dependents is needed. |
|
1263 | 56 |
|
2306 | 57 |
[Warning:] |
58 |
If you use this, be very careful since the collections size changes |
|
59 |
'magically' - for example, testing for being nonEmpty and then |
|
60 |
removing the first element may fail, since the element may vanish inbetween. |
|
61 |
In general, never trust the value as returned by the size/isEmpty messages. |
