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