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. |
| Allocator | Type of allocator for allocating memory of stack. |
|
inline |
Constructor.
| os | Output stream. |
| allocator | User supplied allocator. If it is null, it will create a private one. |
| levelDepth | Initial capacity of stack. |
|
inline |
Writes the given double value to the stream.
| d | The value to be written. |
|
inline |
Checks whether the output is a complete JSON.
A complete JSON has a complete root object or array.
|
inline |
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();
