Method: JSON::Pure::Parser#initialize

Defined in:
lib/json/pure/parser.rb

#initialize(source, opts = {}) ⇒ Parser

Creates a new JSON::Pure::Parser instance for the string source.

It will be configured by the opts hash. 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 19.

  • 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.

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

  • object_class: Defaults to Hash

  • array_class: Defaults to Array

  • quirks_mode: Enables quirks_mode for parser, that is for example parsing single JSON values instead of documents is possible.
