json_value_insert_after Subroutine

private subroutine json_value_insert_after(json, p, element)

Inserts element after p, and updates the JSON structure accordingly.

Example

  program test
   use json_module
   implicit none
   logical(json_LK) :: found
   type(json_core) :: json
   type(json_value),pointer :: p,new,element
   call json%load(file='myfile.json', p=p)
   call json%get(p,'x(3)',element,found) ! get pointer to an array element in the file
   call json%create_integer(new,1,'')    ! create a new element
   call json%insert_after(element,new)   ! insert new element after x(3)
   call json%print(p,'myfile2.json')     ! write it to a file
   call json%destroy(p)                  ! cleanup
  end program test

Details

  • This routine can be used to insert a new element (or set of elements) into an array or object at a specific index. See json_value_insert_after_child_by_index
  • Children and subsequent elements of element are carried along.
  • If the inserted elements are part of an existing list, then they are removed from that list.
              p
       [1] - [2] - [3] - [4]
                 |
                [5] - [6] - [7]        n=3 elements inserted
              element       last

  Result is:

       [1] - [2] - [5] - [6] - [7] - [3] - [4]

Type Bound

json_core

Arguments

Type IntentOptional Attributes Name
class(json_core), intent(inout) :: json
type(json_value), pointer :: p

a value from a JSON structure (presumably, this is a child of an object or array).

type(json_value), pointer :: element

the element to insert after p
