json_file_add Subroutine

private subroutine json_file_add(me, p, destroy_original)

Add a json_value pointer as the root object to a JSON file.

Note

This is mostly equivalent to:

    f = [[json_file]](p)

But without the finalization calls.

And:

    if (destroy_original) call [[json_file]]%destroy()
    call [[json_file]]%add('$',p)

Type Bound

json_file

Arguments

Type IntentOptional Attributes Name
class(json_file), intent(inout) :: me
type(json_value), intent(in), pointer :: p

pointer to the variable to add
logical(kind=LK), intent(in), optional :: destroy_original

if the file currently contains an associated pointer, it is destroyed. [Default is True]
