Detailed Description

Build a StreamWriter implementation.

Usage:

using namespace Json;
Value value = ...;
StreamWriterBuilder builder;
builder["commentStyle"] = "None";
builder["indentation"] = "   ";  // or whatever you like
std::unique_ptr<Json::StreamWriter> writer(
    builder.newStreamWriter());
writer->write(value, &std::cout);
std::cout << std::endl;  // add lf and flush

setDefaults() [1/2]

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)

Remarks

Defaults:

setDefaults() [2/2]

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

Precondition

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

Remarks

Defaults:

validate() [1/2]

bool Json::StreamWriterBuilder::validate

(

Json::Value *

invalid

)

const

Returns

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

validate() [2/2]

Returns

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

Member Data Documentation

settings_

Json::Value Json::StreamWriterBuilder::settings_

Configuration of this builder. Available settings (case-sensitive):

• "commentStyle": "None" or "All"
• "indentation": "<anything>"
• "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".

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