Module ShiftWithJoin.FiniteSupportSource

Infinite products with finite supports. A special case of NearlyConstant.

Parameters

module Base : Semilattice

Signature

include Semilattice
include Shift.S
include StructuredType.PartiallyOrderedType
include StructuredType.EqualityType
Sourcetype t

The type.

Sourceval equal : t -> t -> bool

equal x y checks whether x and y are equivalent.

Sourceval dump : Format.formatter -> t -> unit

Ugly printer.

Sourceval lt : t -> t -> bool

lt x y checks if x is strictly less than y. Note that trichotomy fails for general partial orders.

Sourceval leq : t -> t -> bool

leq x y checks if x is less than or equal to y. Note that trichotomy fails for general partial orders.

Sourceval id : t

id is the unit.

Sourceval is_id : t -> bool

is_id s checks whether s is the unit. It is equivalent to equal id s, but potentially faster.

Sourceval compose : t -> t -> t

compose s1 s2 composes the operators s1 and s2. Note that Foo^s1^s2 in McBride's notation is understood as compose (compose ... s2) s1 with the reversed order.

Sourceval join : t -> t -> t

join x y is the maximum of x and y.

Sourceval of_list : Base.t list -> t

Conversion from a list

Sourceval to_list : t -> Base.t list

Conversion to a list
