Module `S.UnitIndex`

type t

module E : Logtk.Index_intf.EQUATION with type t = Logtk.Term.t * Logtk.Term.t * bool * C.t and type rhs = Logtk.Term.t: 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 Sequence.t -> t
val add_list : t -> E.t list -> t
val remove : t -> E.t -> t
val remove_seq : t -> E.t Sequence.t -> t
val size : t -> int: Number of indexed (in)equations

val iter : t -> (Logtk.Index_intf.term -> E.t -> unit) -> unit: Iterate on indexed equations

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