Interfaces

public interface json_file

Structure constructor to initialize a json_file object with an existing json_value object, and either the json_core settings or a json_core instance.

private function initialize_json_file(p, verbose, compact_reals, print_signs, real_format, spaces_per_tab, strict_type_checking, trailing_spaces_significant, case_sensitive_keys, no_whitespace, unescape_strings) result(file_object)

Author: Izaak Beekman
Date: 07/23/2015

Cast a json_value object as a json_file object. It also calls the initialize() method.
