16 | // Purpose: Single hashed Map. This Map is used to store and |
17 | // retrieve keys in linear time. |
7fd59977 |
18 | // The ::Iterator class can be used to explore the |
19 | // content of the map. It is not wise to iterate and |
20 | // modify a map in parallel. |
7fd59977 |
21 | // To compute the hashcode of the key the function |
22 | // ::HashCode must be defined in the global namespace |
7fd59977 |
23 | // To compare two keys the function ::IsEqual must be |
24 | // defined in the global namespace. |
7fd59977 |
25 | // The performance of a Map is conditionned by its |
26 | // number of buckets that should be kept greater to |
27 | // the number of keys. This map has an automatic |
28 | // management of the number of buckets. It is resized |
29 | // when the number of Keys becomes greater than the |
30 | // number of buckets. |
7fd59977 |
31 | // If you have a fair idea of the number of objects |
32 | // you can save on automatic resizing by giving a |
33 | // number of buckets at creation or using the ReSize |
34 | // method. This should be consider only for crucial |
35 | // optimisation issues. |
