SequenceableCollections have ordered elements which can be accessed via a numeric index. |
40 |
SequenceableCollection is an abstract class - there are no direct instances of it in the system. |
|
1385 | 41 |
|
42 |
The methods found here assume that implementations of (at least) |
|
11272 | 43 |
#at:/#at:put: are implemented (which are always found in Object for indexable objects). |
44 |
||
45 |
For performance, some subclasses redefine more methods, |
|
46 |
knowing the detail of how elements are stored. |
|
47 |
||
8874 | 48 |
Especially, bulk data manipulation (i.e. #replaceFrom:to:with:startingAt:) |
11272 | 49 |
and search methods (i.e. #indexOf:startingAt:) are good candidates for this kind of tuneup. |
50 |
||
51 |
The most heavily used SequentialCollections in the system are probably Array, String, ByteArray |
|
52 |
OrderedCollection and SortedCollection. |
