Detailed Description

A type flow that helps parse ASCII input streams.

Please note that this not a "symmetrical" tflow like all the others, that is you shouldn't use it in building a serialization stack. ie. write_string by printoflow may not always translate to the same read_string in printiflow.

virtual bool scopira::tool::printiflow::read_string ( std::string &  ret,
int  _max 
) [virtual]

Reads a string. Specifically, read the next _max chars into the string. Anything other than _max chars is considered failure.

virtual bool scopira::tool::printiflow::read_string ( std::string &  ) [virtual]

Reads a string. Specifically, the next line of next up to the line terminator. UNIX and Win32 line terminators are supported. The line terminator(s) will NOT be in the resulting string.
