This read-only map returns the sum of the values of the two given maps. Its Key
and Value
types are inherited from M1
. The Key
and Value
of M2
must be convertible to those of M1
.
If m1
is of type M1
and m2
is of M2
, then for
am[x]
will be equal to m1[x]+m2[x]
.
The simplest way of using this map is through the addMap() function.
