Returns the state code of a (possible new state set) `sset`. This may trigger the reallocation of mapping info. nexusSymbol can be '' if there is not a single-character symbol that represents this state set. if `addToLookup` is false and the state set is not found then NXS_INVALID_STATE_CODE will be returned. if the stateset is added with a `nexusSymbol` then the new "symbol" will be case-sensitive (this is an mechanism for entering equates and equates are always case sensitive). New "fundamental" states can NOT be introduced using this function -- if unknown states are encountered, an exception will be generated. Definition at line 2630 of file nxscharactersblock.cpp. |
