module M: Kwmap.Make(sig


type t = string option 




val compare : 'a -> 'a -> int
end)
Maps keyed by optional sections.
include struct ... end
val keys : 'a t -> key list
list of keys in map in ascending order
m : the map
val adjoin : ('a -> 'b -> 'b) -> 'b -> key -> 'a -> 'b t -> 'b t
adjoin vadd empty returns a function f k v m that adjoins v to the collection of values associated with key k. vadd might be cons and empty, [], or S.add and S.empty for some set S.
vadd : vadd v c is a function that adds v to a collection c, returning the extended collection.
empty : is the zero element for vadd
k : key
v : value
m : the map
val append : 'a list t -> key -> 'a -> 'a list t
Deprecated.You should use adjoin.
append v to list of values associated with k
m : the map
k : key
v : value
val size : 'a t -> int
size of map (number of keys)
m : the map
val diff : 'a t -> 'b t -> 'a t
map a minus map b i.e. for each key in b, remove it from a
a : minuend
b : subtrahend
val replace : key -> 'a -> 'a t -> 'a t
replace the mapping for k and v in map m
k : key
v : value
m : the map
val of_list : (key * 'a) list -> 'a t -> 'a t
add a list of (key,value) pairs (i.e. an alist) to a map
Returns a new map extended by the pairs
l : the list of pairs
m : the map to add items to
val values : 'a t -> 'a list
return list of all values in map
Returns the list
m : the map
val intersect : (key -> 'a -> 'b -> 'c) -> 'a t -> 'b t -> 'c t
return the intersection of two maps, based on keys

the value associated with each key in the new map is a function of the (shared) key and the two old values
Returns new intersection map

f : function to apply to the key, the a-value and the b-value
a : first map
b : second map
val union : 'a t -> 'a t -> 'a t
keywise union of two maps
Returns new map which is the union of a and b, keywise, preferring values in b when keys conflict
a : first map
b : second map
val incr : ?i:int -> key -> int t -> int t
use a map value to count a key, adding i to value
Returns new map with incremented k value
i : the increment (default: 1)
k : the key
m : the map
val to_list : 'a t -> (key * 'a) list
create a list (association list) from the items in a map
Returns the list
map : the map
val comparer : ?def:'a -> ?result:int -> (key * 'a) list -> key -> key -> int
generate a Pervasives.compare-compatible comparison function, using the map as a "sort map" Parameters def and result are mutually exclusive.
Returns Pervasives.compare-compatible comparison function
def : default value for any key not in map (default: raise Not_found)
result : default result (~-1,0,1) for any key not in map (default: raise Not_found)
fs : alist of keys paired with sort values
