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