json_failed Function

  2. json_value_module
  3. json_failed

private pure function json_failed(json) result(failed)

Logical function to indicate if an exception has been thrown in a json_core.

Example

    type(json_core) :: json
    type(json_value),pointer :: p
    logical :: status_ok
    character(len=:),allocatable :: error_msg
    call json%parse(filename='myfile.json',p)
    if (json%failed()) then
        call json%check_for_errors(status_ok, error_msg)
        write(*,*) 'Error: '//error_msg
        call json%clear_exceptions()
        call json%destroy(p)
    end if

Note that json_file contains a wrapper for this routine, which is used like:

    type(json_file) :: f
    logical :: status_ok
    character(len=:),allocatable :: error_msg
    call f%load_file(filename='myfile.json')
    if (f%failed()) then
        call f%check_for_errors(status_ok, error_msg)
        write(*,*) 'Error: '//error_msg
        call f%clear_exceptions()
        call f%destroy()
    end if
