Detailed Description

template<typename OutputStream, typename SourceEncoding = UTF8<>, typename TargetEncoding = UTF8<>, typename StackAllocator = CrtAllocator>
class rapidjson::Writer< OutputStream, SourceEncoding, TargetEncoding, StackAllocator >

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().

Template Parameters

OutputStream	Type of output stream.
SourceEncoding	Encoding of source string.
TargetEncoding	Encoding of output stream.
StackAllocator	Type of allocator for allocating memory of stack.

Note

implements Handler concept

Constructor & Destructor Documentation

template<typename OutputStream, typename SourceEncoding = UTF8<>, typename TargetEncoding = UTF8<>, typename StackAllocator = CrtAllocator>

rapidjson::Writer< OutputStream, SourceEncoding, TargetEncoding, StackAllocator >::Writer ( OutputStream &  os, StackAllocator *  stackAllocator = 0, size_t  levelDepth = kDefaultLevelDepth  )

inlineexplicit

Constructor.

Parameters

os	Output stream.
stackAllocator	User supplied allocator. If it is null, it will create a private one.
levelDepth	Initial capacity of stack.

Member Function Documentation

template<typename OutputStream, typename SourceEncoding = UTF8<>, typename TargetEncoding = UTF8<>, typename StackAllocator = CrtAllocator>

bool rapidjson::Writer< OutputStream, SourceEncoding, TargetEncoding, StackAllocator >::Double ( double  d )

inline

Writes the given double value to the stream.

Parameters

d	The value to be written.

Returns

Whether it is succeed.

template<typename OutputStream, typename SourceEncoding = UTF8<>, typename TargetEncoding = UTF8<>, typename StackAllocator = CrtAllocator>

bool rapidjson::Writer< OutputStream, SourceEncoding, TargetEncoding, StackAllocator >::IsComplete ( ) const

inline

Checks whether the output is a complete JSON.

A complete JSON has a complete root object or array.

template<typename OutputStream, typename SourceEncoding = UTF8<>, typename TargetEncoding = UTF8<>, typename StackAllocator = CrtAllocator>

void rapidjson::Writer< OutputStream, SourceEncoding, TargetEncoding, StackAllocator >::Reset ( OutputStream &  os )

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.

Parameters

os	New output stream. Writer<OutputStream> writer(os1); writer.StartObject(); // ... writer.EndObject(); writer.Reset(os2); writer.StartObject(); // ... writer.EndObject();
