Uninterpreted function

Sourceval 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.

Sourceval 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: =

Sourceval 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)

Sourceval 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

Sourceval hash : 'a t -> int

hash t compute the hash value for a term.

  • parameter t

    The term.

  • returns

    The hash value of the term.

Sourceval sort : 'a t -> 'a sort

sort t get the sort of a term.

  • parameter t

    The term.

  • returns

    The sort of the term.

Sourceval pp : Format.formatter -> 'a term -> unit

pp formatter t pretty print term.

  • parameter formatter

    The outpout formatter

  • parameter t

    The term.

Algebraic view of formula terms.

Sourceval view : 'a term -> 'a view

view t destructurate a term.

  • parameter t

    The term.

  • returns

    The view of the term and its children.
