Module NPDtree.Make

Parameters

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 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 -> (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) 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
