Rapidjson output to string not working

I am trying to use rapidjson to output itself to a string to save to a database, using the following code :

StringBuffer buffer;
Writer<FileStream> writer(buffer);
rest.Accept(writer);
string reststring = buffer.GetString();

where rest is a rapidjson::Document.

However I get the following error : 

no matching function for call to ‘rapidjson::Writer<rapidjson::FileStream>::Writer (rapidjson::StringBuffer&)’.

which is strange because the author of rapidjson recommended this method in an answer to a previous SO question.

Solution

  • I must have been tired at 9 last night when I wrote this piece of code.

    Changing 

    Writer<FileStream> writer(buffer);

    to 

    Writer<StringBuffer> writer(buffer);

    solves the problem.
