Graph Key

Nodes of different colours represent the following:

Solid arrows point from a submodule to the (sub)module which it is descended from. Dashed arrows point from a module or program unit to modules which it uses.
Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

Interfaces

public interface json_file

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

Example

 ...
 type(json_file) :: my_file
 type(json_value),pointer :: json_object
 type(json_core) :: json_core_object
 ...
 ! Construct a json_object:
 !could do this:
   my_file = json_file(json_object)
 !or:
   my_file = json_file(json_object,verbose=.true.)
 !or:
   my_file = json_file('{"x": [1]}',verbose=.true.)
 !or:
   my_file = json_file(json_object,json_core_object)
 !or:
   my_file = json_file('{"x": [1]}',json_core_object)

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, comment_char, path_mode, path_separator, compress_vectors, allow_duplicate_keys, escape_solidus, stop_on_error, null_to_real_mode, non_normal_mode, use_quiet_nan, strict_integer_type_checking) 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.

Note

initialize_json_core, json_initialize, initialize_json_core_in_file, initialize_json_file, initialize_json_file_v2, initialize_json_file_from_string, and initialize_json_file_from_string_v2 all have a similar interface.
