Detailed Description

This class is a yyFlexLexer subclass with two pure virtual methods you can override to process identifiers and final types:.

void complete_token(string token, map<string,string> params);

This method is called whenever a complete identifier token has been parsed, with parameters (which will have no contents if there were no parameters. If a key was supplied with no value, the key will be present with an empty string for value. If an empty identifier was given (e.g. "foo;;bar;baz") then this method will be called with an empty string for token (you may then issue an error, warning, or simply ignore it, as you wish). Reserved identifiers (such as "type") are also passed to this method.

void final_type(string token, map<string,string> params);

This method is called once for the final media type identifer token has been parsed, with parameters, analagous to complete_token.
