token_list [constructor] |
Construct a list. |
This container allows iteration of a list of items in a header field value. The input is a comma separated list of tokens. If a parsing error is encountered while iterating the string, the behavior of the container will be as if a string containing only characters up to but excluding the first invalid character was used to construct the list.
token-list = *( "," OWS ) token *( OWS "," [ OWS token ] )
To use this class, construct with the string to be parsed and then use begin
and end
, or range-for to iterate each
item:
for ( auto const & token : token_list{ "apple, pear, banana" }) std::cout << token << "\n" ;
