This read-only map returns the value of the given map multiplied from the left side with a constant value. Its Key
and Value
are inherited from M
.
Actually,
ScaleMap<M> sc(m,v);
is equivalent to
ConstMap<M::Key, M::Value> cm(v); MulMap<ConstMap<M::Key, M::Value>, M> sc(cm,m);
The simplest way of using this map is through the scaleMap() function.
