Main class used to convert QVariant objects to JSON data.
QVariant objects are converted to a string containing the JSON data.
Usage:
The output will be:
It's possible to tune the indentation level of the resulting string.

| void QJson::Serializer::allowSpecialNumbers | ( | bool | allow | ) |
Allow or disallow writing of NaN and/or Infinity (as an extension to QJson)
Definition at line 390 of file serializer.cpp.
| QString QJson::Serializer::errorMessage | ( | ) | const |
Returns the error message

This method generates a textual JSON representation and outputs it to the passed in I/O Device.
| variant | The JSON document in its in-memory representation as generated by the parser. |
| out | Input output device |
| ok | if a conversion error occurs, *ok is set to false; otherwise *ok is set to true |

| QByteArray Serializer::serialize | ( | const QVariant & | variant | ) |
This is a method provided for convenience. It turns the passed in in-memory representation of the JSON document into a textual one, which is returned. If the returned string is empty, the document was empty. If it was null, there was a parsing error.
