Detailed Description

Writes a Value in JSON format in a human friendly way, to a stream rather than to a string.

The rules for line break and indent are as follow:

• Object value:
  • if empty then print {} without indent and line break
  • if not empty the print '{', line break & indent, print one value per line and then unindent and line break and print '}'.
• Array value:
  • if empty then print [] without indent and line break
  • if the array contains no object value, empty array or some other value types, and all the values fit on one lines, then print the array on a single line.
  • otherwise, it the values do not fit on one line, or the array contains object or non empty array, then print one value per line.

If the Value have comments then they are outputed according to their CommentPlacement.

Parameters

indentation

Each level will be indented by this amount extra.

write()

void Json::StyledStreamWriter::write	(	std::ostream &	out,

Serialize a Value in JSON format.

Parameters

out	Stream to write to. (Can be ostringstream, e.g.)
root	Value to serialize.

Note

There is no point in deriving from Writer, since write() should not return a value.
