OrMap< M1, M2 > Class Template Reference

Detailed Description

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

This read-only map returns the logical 'or' of the values of the two given maps. Its Key type is inherited from M1 and its Value type is bool. M2::Key must be convertible to M1::Key.

If m1 is of type M1 and m2 is of M2, then for

OrMap<M1,M2> om(m1,m2);

om[x] will be equal to m1[x]||m2[x].

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