Registries provide an easy interface to using WeakArrays. |
40 |
A class, which wants to be informed of instance-death, can put a created object |

into a registry. The registry will create an executor, which is a (shallow-)copy |

of the object, and watch out for death of the original object. When it dies, |

Stefan Vogel <sv@exept.de>

|
43 |
the executor will be sent a #finalize message. |
69 | 44 |
The trick with the shallow copy is especially nice, you can think of it as |
45 |
being the original object which died. |
|
1 | 46 |
|
69 | 47 |
All objects, which keep external resources (such as fileDescriptors, fonts, |
48 |
colormap-entries etc.) should be registered, so that the underlying resource |
|
49 |
can be freed when the object goes away. |
|
1 | 50 |
|
69 | 51 |
Of course, you too can use it to do whatever you need to do in case of the |
52 |
death of an object. |

54 |
Registries use #executor to aquire the copy of the original, |
14352 | 55 |
this can be redefined in individual classes for faster copying |
56 |
(typically, not all internal state, but only some device handles are needed for |
|
57 |
finalization). If the to-be-registered object is large, this method may also |
|
317 | 58 |
return a stub (placeHolder) object. (i.e. there is no need for the copy to be |

of the same class as the original, as long as it implements #finalize and frees |
14352 | 60 |
the relevant OS resources. Some classes return a specialized private-class instance, |
61 |
which only holds on the handle and implements #finalize.) |

Example uses are found in Form, Color, ExternalStream and Font |
