val remove : t -> elt -> unit
remove v a
removes a
from the domain of v
. Leaves the domain
unchanged if a
does not belong to it.
val values : t -> elt list
values v
returns the list of all integers in the domain of v
. If
v
is instantiated to n
, returns the singleton list containing n
.
val iter : (elt -> unit) -> t -> unit
iter f v
iterates f on each integer in the domain of v
.
