Hi Joaquin,
does this mean that if the zeroth index is unordered or ordered but
non-unique you could have a false negative in the equality test due to
elements ordering being undefined?
Regards,
Francesco.

Hi Ted,
------------------------------ *De:* boost-users-bounces@lists.boost.org [ boost-users-bounces@lists.boost.org] En nombre de Ted Pederson [ ted.pederson@gmail.com] *Enviado el:* viernes, 09 de mayo de 2008 18:03 *Para:* boost-users@lists.boost.org *Asunto:* [Boost-users] testing for multi_index equality
Is there an easy way to test two multi_index containers for equality, c1
== c2?
c1 == c2 is defined to be equivalent to c1.get<0>()==c2.get<0>(), which is defined if the first index of the container is of type ordered, sequenced or random access; in all these cases the expression is in fact equivalent to
c1.size()==c2.size()&&std::equal(c1.begin(),c1.end(),c2.begin());
Is this not what you had in mind?
