Module ProofState.UnitIndex

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

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
