详细描述

Build a CharReader implementation.

Usage:

using namespace Json;
CharReaderBuilder builder;
builder["collectComments"] = false;
Value value;
String errs;
bool ok = parseFromStream(builder, std::cin, &value, &errs);

成员函数说明

newCharReader()

CharReader * nim_cpp_wrapper_util::Json::CharReaderBuilder::newCharReader ( ) const

overridevirtual

Allocate a CharReader via operator new().

异常

std::exception

if something goes wrong (e.g. invalid settings)

实现了 nim_cpp_wrapper_util::Json::CharReader::Factory.

operator[]()

Value & nim_cpp_wrapper_util::Json::CharReaderBuilder::operator[]

(

const String &

key

)

A simple way to update a specific setting.

setDefaults()

void nim_cpp_wrapper_util::Json::CharReaderBuilder::setDefaults ( nim_cpp_wrapper_util::Json::Value *  settings )

static

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

前置条件

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

备注

Defaults:

[CharReaderBuilderDefaults]

[CharReaderBuilderDefaults]

strictMode()

void nim_cpp_wrapper_util::Json::CharReaderBuilder::strictMode ( nim_cpp_wrapper_util::Json::Value *  settings )

static

Same as old Features::strictMode().

前置条件

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

备注

Defaults:

[CharReaderBuilderStrictMode]

[CharReaderBuilderStrictMode]

validate()

bool nim_cpp_wrapper_util::Json::CharReaderBuilder::validate

(

nim_cpp_wrapper_util::Json::Value *

invalid

)

const

返回

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

类成员变量说明

settings_

nim_cpp_wrapper_util::Json::Value nim_cpp_wrapper_util::Json::CharReaderBuilder::settings_

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

• "collectComments": false or true
  • true to collect comment and allow writing them back during serialization, false to discard comments. This parameter is ignored if allowComments is false.
• "allowComments": false or true
  • true if comments are allowed.
• "allowTrailingCommas": false or true
  • true if trailing commas in objects and arrays are allowed.
• "strictRoot": false or true
  • true if root must be either an array or an object value
• "allowDroppedNullPlaceholders": false or true
  • true if dropped null placeholders are allowed. (See StreamWriterBuilder.)
• "allowNumericKeys": false or true
  • true if numeric object keys are allowed.
• "allowSingleQuotes": false or true
  • true if '' are allowed for strings (both keys and values)
• "stackLimit": integer
  • Exceeding stackLimit (recursive depth of readValue()) will cause an exception.
  • This is a security issue (seg-faults caused by deeply nested JSON), so the default is low.
• "failIfExtra": false or true
  • If true, parse() returns false when extra non-whitespace trails the JSON value in the input string.
• "rejectDupKeys": false or true
  • If true, parse() returns false when a key is duplicated within an object.
• "allowSpecialFloats": false or true
  • If true, special float values (NaNs and infinities) are allowed and their values are lossfree restorable.

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