Every class in the system inherits from Behavior (via Class, ClassDescription); |
43 |
so here is where most of the class messages end up being implemented. |
|
44 |
(to answer a FAQ: 'Point basicNew' will be done here :-) |
|
45 |
||
356 | 46 |
Beginners should keep in mind, that all classes are instances (of subclasses) |
12094 | 47 |
of Behavior, therefore you will find the above mentioned 'basicNew:' method |
48 |
under the 'instance'-methods of Behavior - NOT under the class methods |
|
49 |
('Behavior new' will create and return a new class, while sending 'new' to |
|
154 | 50 |
any instance of Behavior (i.e. any class) will return an instance of that class). |
68 | 51 |
|
2226 | 52 |
|
19833 | 53 |
Behavior provides minimum support for all class-like objects, which define behavior |
19943 | 54 |
of other objects. Additional stuff (meta info) is found in ClassDescription and Class. |
55 |
Behavior provides all mechanisms needed to create instances (on the class side), |
|
56 |
and send messages to them. |
|
57 |
However, Behavior does not provide the (symbolic) information needed to compile methods |
|
19833 | 58 |
for a class or to get useful information in inspectors or browsers. |
59 |
||
60 |
For experts: |
|
2226 | 61 |
|
62 |
Since instances of Behavior provide all that is needed to interact with the VM's |
|
63 |
message dispatch mechanism, these can be used as 'light weight' classes. |
|
64 |
I.e. it is possible, to generate completely anonymous classes (and instances thereof) |
|
65 |
on the fly - 'Behavior new new' is such a thingy. |
|

The selectors and methods are organized in a MethodDictionary (which is not a true |
2226 | 68 |
dictionary, but an Array with alternating selector/method entries). |

NOTICE: |
18289 | 102 |
the stuff described below may not be available on other |
103 |
Smalltalk implementations; be aware that these error mechanisms |
|
104 |
are ST/X specials and applications using these (tricks) may |
|
105 |
not be portable to other systems. |

WARNING: |
|
18289 | 108 |
do not try the examples below on (some) other smalltalk systems; |
109 |
it has been reported, that some crash badly when doing this .... ;-) |
|

|
356 | 111 |
Instances of Behavior and subclasses (i.e. in sloppy words: classes) |
112 |
play a special role w.r.t. the VM. Only objects whose class-slot is marked |
|
113 |
as being behaviorLike (in the flag-instvar) are considered to be classLike |
|
114 |
and a message lookup will be done for it in the well known way. |
|
115 |
Thus, if an object has a class for which its class does NOT have |
|
362 | 116 |
this flag bit set, the VM will trigger an error on a message send. |

--------------- |
356 | 121 |
the above lets every object play the role of a class, |
122 |
which has been flagged as behaviorLike in its class's flag. |
|
12094 | 123 |
Thus, you can create arbitrary new classLike objects and have the VM |
356 | 124 |
play with them. |
125 |
This may offer the flexibility to create a totally different object scheme |
|
362 | 126 |
on top of ST/X (for example: Self like objects) where any object can play |
12858
695cbd35ce8a

|
127 |
a classRole for another object or even for itself. |
356 | 128 |
|
2148 | 129 |
[A concrete application of this is found in the Structure class, |
130 |
which creates objects which are their own class !! |
|
12094 | 131 |
This may look to be of theoretical value at first sight, |
132 |
however, such a construct saves memory, by not requiring an extra |
|
2148 | 133 |
class object per Structure object.] |
134 |
||
135 |
Be aware, that the VM trusts the isBehaviorLike flag - IF it is set for some |
|
136 |
object, the VM EXPECTS the object selector and methodDictionaries to be found |
|
362 | 137 |
at the instance positions as defined here. |
138 |
(i.e. instanceVariables with contents and semantic corresponding to |
|
18289 | 139 |
superclass |
140 |
flags |
|
141 |
methodDictionary |
|
362 | 142 |
must be present and have the same instVar-index as here). |
143 |
||
356 | 144 |
The VM (and the system) may crash badly, if this is not the case. |
362 | 145 |
|
356 | 146 |
Since every class in the system derives from Behavior, the flag setting |
357 | 147 |
(and instance variable layout) is correct for all 'normal' classes. |
148 |
If you experiment by creating new behaviorLike objects, please take |
|
149 |
care of this flag. If you want to use the VM's lookup function, the |

instVars 'superclass' and 'methodDictionary' are required |
357 | 151 |
and have to be at the same instVar index. |
