| michael@0 | 15 | /* This class supports case insensitive lookup. |
| michael@0 | 16 | * |
| michael@0 | 17 | * It differs from atom tables: |
| michael@0 | 18 | * - It supports case insensitive lookup. |
| michael@0 | 19 | * - It has minimal footprint by not copying the string table. |
| michael@0 | 20 | * - It does no locking. |
| michael@0 | 21 | * - It returns zero based indexes and const nsCString& as required by its |
| michael@0 | 22 | * callers in the parser. |
| michael@0 | 23 | * - It is not an xpcom interface - meant for fast lookup in static tables. |
| michael@0 | 24 | * |
| michael@0 | 25 | * ***REQUIREMENTS*** |
| michael@0 | 26 | * - It *requires* that all entries in the table be lowercase only. |
| michael@0 | 27 | * - It *requires* that the table of strings be in memory that lives at least |
| michael@0 | 28 | * as long as this table object - typically a static string array. |
