SequenceableCollections have ordered elements which can be accessed via |
|
39 |
a numeric index. |
|
40 |
SequenceableCollection is an abstract class - there are no instances of |
|
1385 | 41 |
it in the system. |
42 |
||
43 |
The methods found here assume that implementations of (at least) |
|
44 |
#at:/#at:put: are implemented (which are always found in Object for |
|
45 |
indexable objects). |
|
46 |
||
47 |
For performance, some subclasses redefine more methods, knowing the details |
|
48 |
of how elements are stored. |
|
49 |
Especially, bulk data manipulation (i.e. #replaceFrom:to:with:startingAt:) |
|
50 |
and search methods (i.e. #indexOf:startingAt:) are good candidates for this |
|
51 |
kind of tuneup. |
|
52 |
||
53 |
See concrete subclasses (such as OrderedCollection, Array or String). |
