Infix operators over a BatMap
val (-->) : 'a BatMap.S.t -> BatMap.S.key -> 'a
map-->key
returns the current binding of key
in map
,
or raises Not_found
. Equivalent to find key map
.
val (<--) : 'a BatMap.S.t -> BatMap.S.key * 'a -> 'a BatMap.S.t
map <-- (key, value)
returns a map containing the same bindings as
map
, plus a binding of key
to value
. If key
was already bound
in map
, its previous binding disappears.
Equivalent to add key value map
.
