15 |
are you tired of using arrays or identityDictionaries, when
|
|
|
16 |
multiple values have to be returned from some method, AND
|
|
|
17 |
you dont want to add many stupid dummy data-holder classes to
|
|
|
18 |
avoid the above ?
|
|
|
19 |
(for example, the value returned by someMethod>>who)
|
|
|
20 |
|
|
|
21 |
Here is a goody to return an object which is class-less,
|
|
|
22 |
only holding some values, and provides a protocol to access
|
|
|
23 |
those fields. In addition, it supports the array-protocol,
|
|
|
24 |
so it can be used as a backward compatible replacement in
|
|
|
25 |
places where arrays were returned.
|
|
|
26 |
|
|
|
27 |
For example, in Method>>who, instead of returning:
|
|
|
28 |
^ Array with:cls with:selector
|
|
|
29 |
you can also return:
|
|
|
30 |
^ Structure with:#containingClass->cls with:#selector->selector
|
|
|
31 |
|
|
|
32 |
and access these values either as:
|
|
|
33 |
retVal at:1 -> returns the cls
|
|
|
34 |
retVal at:2 -> returns the selector
|
|
|
35 |
or (much more convenient and readable) as:
|
|
|
36 |
retVal containingClass
|
|
|
37 |
retVal selector
|
|
|
38 |
|
|
|
39 |
implementation note:
|
|
|
40 |
this is a very tricky (but fully legal) implementation,
|
|
|
41 |
creating an objects which is its own class. Therefore, no additional
|
|
|
42 |
overhead by extra objects is involved.
|
|
|
43 |
|
|
|
44 |
Another prove that smalltalk is a powerful & flexible programming language.
|
|
|
45 |
However, some smalltalk systems crash if your try this ;-)
