ShiftMap< M, C > Class Template Reference

Detailed Description

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

This read-only map returns the sum of the given map and a constant value (i.e. it shifts the map with the constant). Its Key and Value are inherited from M.

Actually,

ShiftMap<M> sh(m,v);

is equivalent to

ConstMap<M::Key, M::Value> cm(v);
AddMap<M, ConstMap<M::Key, M::Value> > sh(m,cm);

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