BatIMap.Infix
Infix operators over a BatIMap
val (-->) : 'a t -> int -> 'a
map-->key
returns the current binding of key
in map
, or
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
Important warning: BatIMap.add
takes an optional argument, eq
that is missing in this operator <--
. As a consequence, using <--
implies the use of Pervasives.(==) as comparison function.
