json_value_remove Subroutine

private subroutine json_value_remove(json, p, destroy)

Remove a json_value (and all its children) from a linked-list structure, preserving the rest of the structure.

Examples

To extract an object from one JSON structure, and add it to another:

     type(json_core) :: json
     type(json_value),pointer :: json1,json2,p
     logical :: found
     !create and populate json1 and json2
     call json%get(json1,'name',p,found)  ! get pointer to name element of json1
     call json%remove(p,destroy=.false.)  ! remove it from json1 (don't destroy)
     call json%add(json2,p)               ! add it to json2

To remove an object from a JSON structure (and destroy it):

     type(json_core) :: json
     type(json_value),pointer :: json1,p
     logical :: found
     !create and populate json1
     call json%get(json1,'name',p,found)  ! get pointer to name element of json1
     call json%remove(p)                  ! remove and destroy it

History

  • Jacob Williams : 12/28/2014 : added destroy optional argument.
  • Jacob Williams : 12/04/2020 : bug fix.

Type Bound

json_core

Arguments

Type IntentOptional Attributes Name
class(json_core), intent(inout) :: json
type(json_value), pointer :: p
logical(kind=LK), intent(in), optional :: destroy

Option to destroy p after it is removed:

  • If destroy is not present, it is also destroyed.
  • If destroy is present and true, it is destroyed.
  • If destroy is present and false, it is not destroyed.
