Abstract superclass for all collections. |
|
42 |
This abstract class provides functionality common to all collections, |
|
43 |
without knowing how the concrete class implements things. Thus, all |
|
44 |
methods found here depend on some basic mechanisms to be defined in the |
|
45 |
concrete class. |
|
46 |
These basic methods are usually defined as #subclassResponsibility here. |
|
47 |
Some methods are also redefined for better performance. |
|
1289 | 48 |
|
1325 | 49 |
Subclasses should at least implement: |
50 |
do: - enumerate elements |
|
51 |
||
52 |
they should implement one of the following set of access messages: |
|
53 |
keyed collections: |
|
54 |
at:ifAbsent: - fetching an element |
|
55 |
at: - fetching an element |
|
56 |
at:put: - storing an element |
|
57 |
||
58 |
unkeyed collections: |
|
59 |
add: - add an element |
|
60 |
remove:ifAbsent: - remove an element |
|
