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);

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.
