This read-only map returns the negative of the values of the given map (using the unary -
operator). Its Key
and Value
are inherited from M
.
If M::Value is int
, double
etc., then
NegMap<M> neg(m);
is equivalent to
ScaleMap<M> neg(m,-1);
The simplest way of using this map is through the negMap() function.
