Detailed Description

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

This read-write 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. It can also be used as write map if the / operator is defined between Value and C and the given multiplier is not zero.

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