a Dictionary is (conceptionally) a set of Associations storing key-value pairs. |
|
39 |
(The implementation uses two arrays to store the keys and values separately.) |
|
40 |
Searching for an element is done using a hash into the key array. |
|
362 | 41 |
Another way of looking at a dictionary is as a array which uses |
345 | 42 |
arbitrary access keys (i.e. not just integers as arrays do). |
43 |
||
44 |
Since the keys are unordered, no internal element order is defined |
|
362 | 45 |
(i.e. enumerating them may return elements in any order - even changing |
345 | 46 |
over time). |
47 |
||
68 | 48 |
Many methods for searching and hashing are inherited from Set. |
92 | 49 |
|
1279 | 50 |
[Instance variables:] |
345 | 51 |
|
1279 | 52 |
keyArray <Array> (from Set) the keys |
53 |
||
54 |
valueArray <Array> the values ('valueArray at:index' corresponds |
|
55 |
to the value stored under 'keyArray at:index') |
|
92 | 56 |
|
345 | 57 |
Performance hints: |
362 | 58 |
since the dictionary does not really store associations internally, |
59 |
it is less efficient, to store/retrieve associations. The reason is |
|
399 | 60 |
that these assocs are created temporarily in some extract methods. |
345 | 61 |
I.e. 'at:key put:value' is faster than 'add:anAssoc' |
62 |
and 'keysAndValuesDo:' is faster than 'associationsDo:' etc. |
|
92 | 63 |
|
362 | 64 |
If only symbols or smallIntegers are used as keys, use IdentityDictionaries |
65 |
for slightly better performance, since both hashing and comparison is faster. |
|
345 | 66 |
|
67 |
If you have a rough idea how big the dictionary is going to grow, |
|
68 |
create it using #new: instead of #new. Even if the size given is a |
|
69 |
poor guess (say half of the real size), there is some 20-30% performance |
|
70 |
win to expect, since many resizing operations are avoided when associations |
|
71 |
are added. |
