JSON writer.
Writer implements the concept Handler. It generates JSON text by events to an output os.
User may programmatically calls the functions of a writer to generate JSON text.
On the other side, a writer can also be passed to objects that generates events,
for example Reader::Parse() and Document::Accept().
OutputStream | Type of output stream. |
SourceEncoding | Encoding of source string. |
TargetEncoding | Encoding of output stream. |
StackAllocator | Type of allocator for allocating memory of stack. |

Reset the writer with a new stream.
This function reset the writer with a new stream and default settings, in order to make a Writer object reusable for output multiple JSONs.
os | New output stream. Writer<OutputStream> writer(os1);
writer.StartObject();
// ...
writer.EndObject();
writer.Reset(os2);
writer.StartObject();
// ...
writer.EndObject();

Sets the maximum number of decimal places for double output.
This setting truncates the output with specified number of decimal places.
For example,
The default setting does not truncate any decimal places. You can restore to this setting by calling
