ConstMap< K, V > Class Template Reference

Detailed Description

template<typename K, typename V>
class lemon::ConstMap< K, V >

This readable map assigns a specified value to each key.

In other aspects it is equivalent to NullMap. So it conforms to the ReadWriteMap concept, but it absorbs the data written to it.

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