A converter from symbols (strings) to int indices.
This symbol table implementation always adds symbols to its internal symbol table and never removes them.

’s, but underlyingly there is a static map, so multiple instances of this class are all “viewing” the same static data structure, hence the name of this Symbols implementation. Definition at line 120 of file symbol-table.H.
