Re: [Cppcms-users] In json.cpp and json.h I did not seethedeclareof the parse_stream function but you use it onjson.cpp in 1051line.why /?

[4. <440...@qq...>]

I do not understand the exact scope of the anonymous namespace . the anonymous namespace in json namespace,the json namespace in cppcms namespace .
bool value::load(std::istream &in,bool full,int *line_number)
{
		int err_line;
		value v;
		if(!parse_stream(in,*this,full,err_line)) {
			if(line_number)
				*line_number=err_line;
			return false;
		}
		return true;


}  in json namespace


can you explain that why in json namespace can invoke the method in a the anonymous namespace that define in json namespace  ? is the parse_stream just belong json.cpp   ?

                   Why don't you crawl through the sourcecode?
     
     Line 41 + 42 namespace cppcms {
     namespace json {
     
     Line 559 namespace { (anonymous namespace
     
     If you go through the json.h you see, that there isn't any method     parse_stream, that means it is a function in a way that is only     declared in the anonymous namespace from line 559 to 1046 and not a     class method.

             I konw it in 836,but I think it should  bool               value::parse_stream(std::istream &in,value               &out,bool force_eof,int &error_at_line),but not                bool parse_stream(std::istream &in,value               &out,bool force_eof,int &error_at_line) ? I don               not now why.?

                 as you can see it's a method declared in line 836.
                 Did you use Strg+F?
