Structure

*************

type t

Type of an abstract elements.

val bottom : t

Least abstract element of the lattice.

val top : t

Greatest abstract element of the lattice.

Predicates

**************

val is_bottom : t -> bool

is_bottom a tests whether a is bottom or not.

val subset : t -> t -> bool

Partial order relation. subset a1 a2 tests whether a1 is related to (or included in) a2.

Operators

*************

val join : t -> t -> t

join a1 a2 computes an upper bound of a1 and a2.

val meet : t -> t -> t

meet a1 a2 computes a lower bound of a1 and a2.

val widen : 'a Core.Context.ctx -> t -> t -> t

widen ctx a1 a2 computes an upper bound of a1 and a2 that ensures stabilization of ascending chains.

Printing

************

val print : Core.Print.printer -> t -> unit

Printer of an abstract element.
