json_is_vector Function

private function json_is_vector(json, p) result(is_vector)

Returns true if all the children are the same type (and a scalar). Note that integers and reals are considered the same type for this purpose. This routine is used for the compress_vectors option.

Type Bound

json_core

Arguments

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

Return Value logical(kind=LK)

if all elements of a vector are scalars of the same type
