json_value_get_child_by_index Subroutine

private subroutine json_value_get_child_by_index(json, p, idx, child, found)

Returns a child in the object or array given the index.

Type Bound

json_core

Arguments

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

object or array JSON data
integer(kind=IK), intent(in) :: idx

index of the child (this is a 1-based Fortran style array index).
type(json_value), pointer :: child

pointer to the child
logical(kind=LK), intent(out), optional :: found

true if the value was found (if not present, an exception will be thrown if it was not found. If present and not found, no exception will be thrown).
