NullMap< K, V > Class Template Reference
[Maps]
Detailed Description
template<typename K, typename V>
class lemon::NullMap< K, V >
This map can be used if you have to provide a map only for its type definitions, or if you have to provide a writable map, but data written to it is not required (i.e. it will be sent to /dev/null). It conforms to the ReadWriteMap concept.
