ScaleMap< M, C > Class Template Reference

Detailed Description

template<typename M, typename C = typename M::Value>
class lemon::ScaleMap< M, C >

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);
Scales a map with a constant.
Definition maps.h:1105

is equivalent to

Constant map.
Definition maps.h:101
Product of two maps.
Definition maps.h:902

The simplest way of using this map is through the scaleMap() function.
