Argumentoptions, if given, contains a Hash of options for both parsing and generating. SeeParsing Options, andGenerating Options.

For generation, thestrict: true option is always set. When a Ruby object with no native JSON counterpart is encountered, the block provided to the initialize method is invoked, and must return a Ruby object that has a native JSON counterpart:

Serialize the given object into a JSON document.

# File ext/json/lib/json/common.rb, line 1073defload(source)@parser_config.parse(source)end

Parse the given JSON document and return an equivalent Ruby object.

# File ext/json/lib/json/common.rb, line 1082defload_file(path)load(File.read(path,encoding:Encoding::UTF_8))end

Parse the given JSON document and return an equivalent Ruby object.
