NegWriteMap< M > Class Template Reference

Detailed Description

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

This read-write map returns the negative of the values of the given map (using the unary - operator). Its Key and Value are inherited from M. It makes also possible to write the map.

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

*    NegWriteMap<M> neg(m);
*  

is equivalent to

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

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