Boost algorithm split
WebMar 31, 2016 · Boost's tokenize is even more horrific in the aspect of speed. It took 11 seconds with 10 delimiters to split a string into 1.5*10^6 elements. So I don't know what to do: I want to have a really fast string splitting algorithm with multiple delimiters. Is Boost's split the maximum or is there a way to do it faster? WebThis function is equivalent to C strtok. Input sequence is split into tokens, separated by separators. Separator is an every match of the given regex. Each part is copied and added as a new element to the output container. Thus the result container must be able to hold copies of the matches (in a compatible structure like std::string) or a ...
