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