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<X> sc(x,v);

is equivalent to

       ConstMap<X::Key, X::Value> c_tmp(v);
       MulMap<X, ConstMap<X::Key, X::Value> > sc(x,v);
