Symbol_test Class Reference

Description

Test:

properties of Literal and Symbol data types.

• a lib::Literal is just a thin wrapper for a const char *
• lib::Symbol uses the same implementation, but relies on character string constants interned into a symbol table.

  Todo:

  2023 this test is very much in preliminary shape, as the implementation of a real symbol table remains was lacking. At some point, a simplistic implementation of »interned strings« was added (TICKET #157) — yet still the actual relevance of unique Symbols remains nebulous

Test:

use Literal and Symbol as keys in a tree map.

Note

neither Literal, nor Symbol defines an operator< so the map specialisation has to fall back on const char*, which are compared based on pointer identity. Contrast this with std::string, which does define its own ordering.
