type key = t

The type of the map keys.

type +'a t

The type of maps from type key to type 'a.

val hash_fold_t : 'a Map_intf.pvar Base.Hash.folder -> 'a Map_intf.pvar t Base.Hash.folder
val empty : 'a Map_intf.pvar t

The empty map.

val is_empty : 'a Map_intf.pvar t -> bool

Test whether a map is empty or not.

val mem : key -> 'a Map_intf.pvar t -> bool

mem x m returns true if m contains a binding for x, and false otherwise.

val add : key -> 'a Map_intf.pvar -> 'a Map_intf.pvar t -> 'a Map_intf.pvar t

add x y m returns a map containing the same bindings as m, plus a binding of x to y. If x was already bound in m, its previous binding disappears.

val singleton : key -> 'a Map_intf.pvar -> 'a Map_intf.pvar t

singleton x y returns the one-element map that contains a binding y for x.

val remove : key -> 'a Map_intf.pvar t -> 'a Map_intf.pvar t

remove x m returns a map containing the same bindings as m, except for x which is unbound in the returned map.

merge f m1 m2 computes a map whose keys is a subset of keys of m1 and of m2. The presence of each such binding, and the corresponding value, is determined with the function f.

val compare : ('a Map_intf.pvar -> 'a Map_intf.pvar -> int) -> 'a Map_intf.pvar t -> 'a Map_intf.pvar t -> int

Total ordering between maps. The first argument is a total ordering used to compare data associated with equal keys in the two maps.

equal cmp m1 m2 tests whether the maps m1 and m2 are equal, that is, contain equal keys and associate them with equal data. cmp is the equality predicate used to compare the data associated with the keys.

val iter : (key -> 'a Map_intf.pvar -> unit) -> 'a Map_intf.pvar t -> unit

iter f m applies f to all bindings in map m. f receives the key as first argument, and the associated value as second argument. The bindings are passed to f in increasing order with respect to the ordering over the type of the keys.

val fold : (key -> 'a Map_intf.pvar -> 'b -> 'b) -> 'a Map_intf.pvar t -> 'b -> 'b

val for_all : (key -> 'a Map_intf.pvar -> bool) -> 'a Map_intf.pvar t -> bool

for_all p m checks if all the bindings of the map satisfy the predicate p.

Return the number of bindings of a map.

val bindings : 'a Map_intf.pvar t -> (key * 'a Map_intf.pvar) list

Return the list of all bindings of the given map. The returned list is sorted in increasing order with respect to the ordering Ord.compare, where Ord is the argument given to Extmap.Make.

val min_binding : 'a Map_intf.pvar t -> key * 'a Map_intf.pvar

Return the smallest binding of the given map (with respect to the Ord.compare ordering), or raise Not_found if the map is empty.

val max_binding : 'a Map_intf.pvar t -> key * 'a Map_intf.pvar

Same as Extmap.S.min_binding, but returns the largest binding of the given map.

val choose : 'a Map_intf.pvar t -> key * 'a Map_intf.pvar

Return one binding of the given map, or raise Not_found if the map is empty. Which binding is chosen is unspecified, but equal bindings will be chosen for equal maps.

val split : key -> 'a Map_intf.pvar t -> 'a Map_intf.pvar t * 'a Map_intf.pvar option * 'a Map_intf.pvar t

split x m returns a triple (l, data, r), where l is the map with all the bindings of m whose key is strictly less than x; r is the map with all the bindings of m whose key is strictly greater than x; data is None if m contains no binding for x, or Some v if m binds v to x.

val find : key -> 'a Map_intf.pvar t -> 'a Map_intf.pvar

find x m returns the current binding of x in m, or raises Not_found if no such binding exists.

val map : ('a Map_intf.pvar -> 'b Map_intf.pvar) -> 'a Map_intf.pvar t -> 'b Map_intf.pvar t

map f m returns a map with same domain as m, where the associated value a of all bindings of m has been replaced by the result of the application of f to a. The bindings are passed to f in increasing order with respect to the ordering over the type of the keys.

val mapi : (key -> 'a Map_intf.pvar -> 'b Map_intf.pvar) -> 'a Map_intf.pvar t -> 'b Map_intf.pvar t

Same as Extmap.S.map, but the function receives as arguments both the key and the associated value for each binding of the map.
