Build a StreamWriter implementation. More...

#include <json/writer.h>

Inherits Json::StreamWriter::Factory.

Build a StreamWriter implementation.

Usage:

Value value = ...;

builder["commentStyle"] = "None";

builder["indentation"] = " ";

std::unique_ptr<Json::StreamWriter> writer(

builder.newStreamWriter());

writer->write(value, &std::cout);

std::cout << std::endl;

StreamWriterBuilder()

Definition: json_writer.cpp:1161

JSON (JavaScript Object Notation).

Definition: allocator.h:14

◆ StreamWriterBuilder() Json::StreamWriterBuilder::StreamWriterBuilder ( ) ◆ ~StreamWriterBuilder() Json::StreamWriterBuilder::~StreamWriterBuilder ( ) overridedefault ◆ newStreamWriter() StreamWriter * Json::StreamWriterBuilder::newStreamWriter ( ) const overridevirtual ◆ operator[]() Value & Json::StreamWriterBuilder::operator[] ( const String & key )

A simple way to update a specific setting.

◆ setDefaults() void Json::StreamWriterBuilder::setDefaults ( Json::Value * settings ) static

Called by ctor, but you can use this to reset settings_.

Precondition: 'settings' != NULL (but Json::null is fine)

[StreamWriterBuilderDefaults]

◆ validate() bool Json::StreamWriterBuilder::validate ( Json::Value * invalid ) const

Returns: true if 'settings' are legal and consistent; otherwise, indicate bad settings via 'invalid'.

◆ settings_

Configuration of this builder.

Available settings (case-sensitive):

"commentStyle": "None" or "All"
"indentation": "<anything>".
Setting this to an empty string also omits newline characters.
"enableYAMLCompatibility": false or true
slightly change the whitespace around colons
"dropNullPlaceholders": false or true
Drop the "null" string from the writer's output for nullValues. Strictly speaking, this is not valid JSON. But when the output is being fed to a browser's JavaScript, it makes for smaller output and the browser can handle the output just fine.
"useSpecialFloats": false or true
If true, outputs non-finite floating point values in the following way: NaN values as "NaN", positive infinity as "Infinity", and negative infinity as "-Infinity".
"precision": int
Number of precision digits for formatting of real values.
"precisionType": "significant"(default) or "decimal"
Type of precision for formatting of real values.

You can examine 'settings_` yourself to see the defaults. You can also write and read them just like any JSON Value.
