NegMap< M > Class Template Reference

Detailed Description

template<typename M>
class lemon::NegMap< M >

This read-only map returns the negative of the values of the given map (using the unary - operator). Its Key and Value are inherited from M.

If M::Value is int, double etc., then

*    NegMap<M> neg(m);
*  

is equivalent to

*    ScaleMap<M> neg(m,-1);
*  

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