logtk

Core types and algorithms for logic
IN THIS PACKAGE
Module Logtk . Dtree . Make

Parameters

module E : Index.EQUATION

Signature

type t
module E = E

Module that describes indexed equations

type rhs = E.rhs

Right hand side of equation

val empty : unit -> t
val is_empty : t -> bool
val add : t -> E.t -> t

Index the given (in)equation

val add_seq : t -> E.t Iter.t -> t
val add_list : t -> E.t list -> t
val remove : t -> E.t -> t
val remove_seq : t -> E.t Iter.t -> t
val size : t -> int

Number of indexed (in)equations

val iter : t -> ( Index_intf.term -> E.t -> unit ) -> unit

Iterate on indexed equations

val retrieve : ?subst:Index_intf.subst -> sign:bool -> t Scoped.t -> Index_intf.term Scoped.t -> (Index_intf.term * rhs * E.t * Index_intf.subst) Iter.t

retrieve ~sign (idx,si) (t,st) acc iterates on (in)equations l ?= r of given sign and substitutions subst, such that subst(l, si) = t. It therefore finds generalizations of the query term.

val to_dot : t CCFormat.printer

print the index in the DOT format
