ForkMap< M1, M2 > Class Template Reference

Detailed Description

template<typename M1, typename M2>
class lemon::ForkMap< M1, M2 >

This map has two writable map parameters and each write request will be passed to both of them. If M1 is also readable, then the read operations will return the corresponding values of M1.

The Key and Value types are inherited from M1. The Key and Value of M2 must be convertible from those of M1.

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