Module Once.Term

type 'a t = 'a term constraint 'a = [< bv | rm | fp | ('b'c) ar ]

A term of 'a kind.

type 'a variadic =

Uninterpreted function

val const : 'a sort -> string -> 'a term

const sort symbol create a (first-order) constant of given sort with given symbol.

This creates a 0-arity function symbol.

parameter sort

The sort of the constant.

parameter symbol

The symbol of the constant.

returns

A term representing the constant.

val equal : 'a t -> 'a t -> bv t

equal t0 t1 create an equality term.

parameter t0

The first term.

parameter t1

The second term.

returns

SMT-LIB: =

val distinct : 'a t -> 'a t -> bv t

distinct t0 t1 create an disequality term.

parameter t0

The first term.

parameter t1

The second term.

returns

SMT-LIB: not (= t0 t1)

val ite : bv t -> 'a t -> 'a t -> 'a t

ite t0 t1 t2 create an if-then-else term.

parameter t0

The condition term.

parameter t1

The then term.

parameter t2

The else term.

returns

SMT-LIB: ite

val hash : 'a t -> int

hash t compute the hash value for a term.

parameter t

The term.

returns

The hash value of the term.

val sort : 'a t -> 'a sort

sort t get the sort of a term.

parameter t

The term.

returns

The sort of the term.

val pp : Stdlib.Format.formatter -> 'a term -> unit

pp formatter t pretty print term.

parameter formatter

The outpout formatter

parameter t

The term.
