Class type

Functors for generic lattices implementations.

exception Error_Top

Raised by some functions when encountering a top value.

exception Error_Bottom

Raised by Lattice_Base.project.

exception Not_less_than

Raised by Lattice.cardinal_less_than.

exception Can_not_subdiv

Used by other modules e.g. Fval.subdiv_float_interval.

type truth =
  1. | True
  2. | False
  3. | Unknown
    (*

    Truth values with a possibility for 'Unknown'

    *)
val inv_truth : truth -> truth
module Comp : sig ... end

Signatures for comparison operators ==, !=, <, >, <=, >=.

module Int : sig ... end
module Rel : sig ... end

"Relative" integers. They are subtraction between two absolute integers

See e.g. base.ml and locations.ml to see how this functor should be applied. The O module passed as argument is the same as O in the result. It is passed here to avoid having multiple modules calling Hptset.Make on the same argument (which is forbidden by the datatype library, and would cause hashconsing problems)
