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);

Value & operator[] ( JSONCPP_STRING  key )

A simple way to update a specific setting.

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: src/lib_json/json_reader.cpp CharReaderBuilderDefaults

void strictMode ( Json::Value *  settings ) [static]

Same as old Features::strictMode().

Precondition:

Remarks:
Defaults: src/lib_json/json_reader.cpp CharReaderBuilderStrictMode

bool validate ( Json::Value *  invalid ) const
Returns:
true if 'settings' are legal and consistent; otherwise, indicate bad settings via 'invalid'.

Field Documentation

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`
  • `"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.
