type t

module E : 
  Logtk.Index_intf.EQUATION
    with type t = Logtk.Term.t * Logtk.Term.t * bool * C.t
    with 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 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 -> (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) 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
