|size_t||hash ( const LString s )|
To do this, we need several things:
-- A hash table that operates over strings. -- A string broker. This will have functions like 'newstring', 'deletestring', 'copystring', etc. This component will presumably be coupled with the hash table.
-- The LStrings need to talk to the broker. If two strings are concatenated, then they form a new LString which needs to be hashed up and put in the broker, then returned as a new string.
