Constructor Details

#new(opts) ⇒ Object

Creates a new JSON::Ext::ParserConfig instance.

It will be configured by the opts hash. opts can have the following keys:

opts can have the following keys:

  • max_nesting: The maximum depth of nesting allowed in the parsed data structures. Disable depth checking with :max_nesting => false|nil|0, it defaults to 100.

  • allow_nan: If set to true, allow NaN, Infinity and -Infinity in defiance of RFC 4627 to be parsed by the Parser. This option defaults to false.

  • symbolize_names: If set to true, returns symbols for the names (keys) in a JSON object. Otherwise strings are returned, which is also the default. It’s not possible to use this option in conjunction with the create_additions option.

  • create_additions: If set to false, the Parser doesn’t create additions even if a matching class and create_id was found. This option defaults to false.

  • object_class: Defaults to Hash. If another type is provided, it will be used instead of Hash to represent JSON objects. The type must respond to new without arguments, and return an object that respond to []=.

  • array_class: Defaults to Array If another type is provided, it will be used instead of Hash to represent JSON arrays. The type must respond to new without arguments, and return an object that respond to <<.

  • decimal_class: Specifies which class to use instead of the default

    (Float) when parsing decimal numbers. This class must accept a single
string argument in its constructor.
