Detailed Description

Build a CharReader implementation.

Usage:

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

Member Function Documentation

newCharReader()

CharReader* newCharReader ( ) const

virtual

Allocate a CharReader via operator new().

Exceptions

std::exception

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

Implements CharReader::Factory.

setDefaults()

static void 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:

strictMode()

static void strictMode ( Json::Value *  settings )

static

Same as old Features::strictMode().

Precondition

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

Remarks

Defaults:

validate()

bool validate

(

Json::Value *

invalid

)

const

Returns

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

Member Data Documentation

settings_

Json::Value 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.
• "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.
